Reference on Hydrogenation of Alcohols
« Reply #80 on: October 14, 2004, 05:26:00 AM »
This is a reference on hydrogenation of alcohols..........it may apply to amino alcohols, not sure....java

Bull. Chem. Soc. Japan (1960) Vol 33, Pg 1356


In following a lead from an old post from Labrat as to the use of RP/I in the reduction of OH , nitrites , halogens to the alkane......as in the use of primary amino alcohols:

The reactivity of gamma-hydroxybutyric acid (GHB) and gamma-butyrolactone (GBL) in alcoholic solutions
Hennessy SA, Moane SM, McDermott SD, Journal of Forensic Sciences, Vol. 49(6), [10 pages] (2004)
DOI:

10.1520/JFS2003340



Abstract
In this work the stability of GBL (gamma-butyrolactone) and GHB (gamma-hydroxybutyric acid) in alcoholic media was studied. Under acidic conditions the GBL will react with ethanol or methanol to give the corresponding ethyl and methyl esters of GHB. It can be seen that ester formation is dependent on the type of alcohol, the alcohol content of the solution, and the pH of the solution. Under the same conditions it was shown that GHB does not give rise directly to the corresponding ester when merely in the presence of an alcohol; however the ester will be formed if the conditions are present for conversion of GHB to GBL followed by subsequent reaction with alcohol. In alcoholic beverage samples spiked with GBL the expected conversion to GHB occurred, and the formation of the ethyl ester of GHB was also seen in some samples. Wine samples were analyzed for the presence of the ethyl ester of GHB, and the effect of adding GHB/GBL to hot beverages was studied.

If someone could dig this one up, would be appreciated greatly.  :)

Cawley and Hall, J. Soc. Chem. Ind. (London), 62, 116 (1943)

It is an article concerning the hydrogenation of thiophene to tetrahydrothiophene utilizing Molybdenum Disulfide.  Concurrently, any other articles dealing with MoS2 as a hydrogenation catalyst would be most helpful.  TIA.

High atomic yield bromine-less benzylic bromination
Ramon Mestres* and Jesús Palenzuela
Green Chemistry, 2002, 4, 314–316

A two-phase mixture (sodium bromide, aqueous hydrogen peroxide/carbon tetrachloride or chloroform) under visible light provides a simple and convenient system for benzylic bromination of toluenes. A high atomic yield for bromine atoms is attained. Substitution of the chlorinated solvents by other more environmentally benign organic solvents has been attempted and good results are obtained for methyl pivalate.



Aqueous N-alkylation of amines using alkyl halides: direct generation of tertiary amines under microwave irradiation
Yuhong Ju and Rajender S. Varma
Green Chemistry , 2 0 0 4 , 6 , 2 1 9 – 2 2 1

Direct formation of tertiary amines via N-alkylation of amines by alkyl halides occurs in aqueous media under microwave irradiation. This greener alternative is also a useful and powerful method to construct C–N bond without using any transition metal catalysts.



Direct mono-N-alkylation of amines in ionic liquids: chemoselectivity and reactivity
Cinzia Chiappe* and Daniela Pieraccini
Green Chemistry, 2003, 5, 193–197

A simple method for the N-alkylation of primary amines was developed using ionic liquids as solvent in order to prepare secondary amines selectively. In ionic liquids overalkylation of the initially produced secondary amines is in general markedly reduced. Various amines, alkyl halides and sulfonates were examined. The observed selectivities between mono- and dialkylation are typically on the order of 9+1, or higher. Only in the cases of allyl or benzyl bromides does the reaction give the corresponding tertiary amines exclusively. The relative nucleofugality of chloride, bromide, iodide and tosylate with several primary amines was also evaluated, as well as the effect of caesium hydroxide.

"J.Chem.Soc." ?
« Reply #88 on: October 23, 2004, 06:45:00 PM »
Dear Capn, I really would like to help you, but:

are you sure about the journal titles? I have access to 17(!) online journals all carring "journal","chemical" and "society" in their titles (including the famous "Journal of the Serbian Chemical Society", so if anyone needs anything related to serbic chemistry, let me know...  ;D ) - but none of them is called "Journal of (the) Chemical Society" alone...

And the assumption that it might perhaps be JACS was qickly proven wrong by the fact that there exists no "JACS vol.16 p.302" ...  :(

If there exists a journal being really abbreviated with J.Chem.Soc., I would like to know it of course, to avoid such misapprehension next time then...

Vapor Phase Dehydrationof Alcohols
« Reply #96 on: October 26, 2004, 03:00:00 PM »
Would like to read these two articles , to facilitate my understanding of dehydration of primary alcohols in wanting to avoid re-arrangement. I'm trying to reduce Phenyalaninol to the alkene which will then be reduced to the alkane via catalytic hydrogenation....java



In dehydration of alcohols, if the alcohol can be evaporated, vapor phase elimination over AL2O3 is an excellent method since side reactions are greatly reduced

World Market for Rye Ergot
« Reply #97 on: October 28, 2004, 04:39:00 AM »
The following is an e-Book, not journal article, however this seemes like the most appropriate place to post my request.  For the paltry fee of $795.00, Amazon.com will let you download "The World Market for Rye Ergot Alkaloids, Their Derivatives, and Salts Thereof: A 2004 Global Trade Perspective" as a pdf. 

"This report was created for strategic planners, international executives and import/export managers who are concerned with the market for rye ergot alkaloids, their derivatives, and salts thereof...On the demand side, exporters and strategic planners approaching the world market face a number of questions. Which countries are supplying rye ergot alkaloids, their derivatives, and salts thereof? What is the dollar value of these imports? How much do the imports of rye ergot alkaloids, their derivatives, and salts thereof vary from one country to another? Do exporters serving the world market have similar market shares across the importing countries? Which countries supply the most exports of rye ergot alkaloids, their derivatives, and salts thereof? Which countries are buying their exports? What is the value of these exports and which countries are the largest buyers?"

(On the off chance) Any beeshave access to this file?

Inactivation of 5-HT2C Receptors Potentiates Consequences of Serotonin Reuptake Blockade
Thomas I F H Cremers, Marco Giorgetti, Fokko J Bosker, Sandra Hogg, Jørn Arnt, Arne Mørk, Gerard Honig, Klaus-Peter Bøgesø, Ben H C Westerink, Hans den Boer, Hkan V Wikstrom and Laurence H Tecott

Abstract: The enhancement of central serotonin system function underlies the therapeutic effects of selective serotonin reuptake inhibitors (SSRIs), which have become the most commonly used class of antidepressant agents. However, many individuals experience depressive episodes that are resistant to SSRI treatment. Homeostatic mechanisms that limit the extent to which SSRIs enhance serotonergic neurotransmission have been implicated in this phenomenon. Here, we report a novel strategy for enhancing the efficacy of SSRIs. Using in vivo microdialysis methods in rats, the nonselective 5-HT2 receptor antagonist ketanserin was observed to produce a robust augmentation of citalopram-, fluoxetine-, and sertraline-induced elevations of hippocampal extracellular serotonin levels. Similar effects were also observed in cortex. The potentiation of SSRI-induced increases in hippocampal serotonin levels was reproduced by the 5-HT2C receptor-selective antagonists SB 242084 and RS 102221, but not by the 5-HT2A receptor-selective antagonist MDL 100 907. Although 5-HT2C receptor antagonists augmented the actions of SSRIs, they had no effect on extracellular serotonin levels or tail suspension responses when administered alone. These results were in strong accord with independent findings using a line of 5-HT2C receptor-null mutant mice. Although this mutation did not affect baseline extracellular serotonin levels or tail suspension test (TST) behavior, it enhanced fluoxetine effects on serotonin levels and immobility in the TST. These findings reveal an unanticipated pharmacological action of 5-HT2C receptors that warrants consideration in the development of novel strategies for the treatment of depression.
