Title: CHEM_GUY's top new articles to research!
Post by: jim on January 18, 2001, 06:50:00 PM: Here's a couple new articles I ran across that someone might feel the need to research further. ( I am paraphaseing the title )

Reductions of azides using FeCl3-Zn
Chem. Lett. 2000(7), page 817

Ni catalyzed formic acid reductions of nitro compounds
Synth. Commun. 2000, 30(16), page 2884

Microwave assisted methods for the conversion of aldehydes into nitriles
Syth. Commun., 200, 30(17), page 3019

Mircowave chemistry with poly(ethylnen glycols) as solvent...
Tetrahedron Letters, 200, 41(33), page 6371

Good luck!

You're the best!!! Please keep the new info coming!!!!!

Watch for a new MDA snynth using the above mentioned FeCl3/Zn reduction in a week or so!

I'm specially interested in :

Ni catalyzed formic acid reductions of nitro compounds
Synth. Commun. 2000, 30(16), page 2884

Microwave assisted methods for the conversion of aldehydes into nitriles
Syth. Commun., 200, 30(17), page 3019

I would appreciate if someone could post it in the Hive, it's not available around here.

Post by: jim on January 22, 2001, 05:21:00 PM: Ritter, I am glad you liked that article.

Sunlight I am glad you're interested, but last time I check you lived in Tucson, so why don' you go to the University of Arizona library (science and Engineering) and look up the articles yourself and post it from the library computer terminals... I am pretty sure that the library has them. Call number QD262. S395

I looked up the mircowave article on poly ethylene glycols (PEGs). A pretty good reference. PEGs can be used as phase transfer catalysts (PTCs). Thats right, regular old brake fuild. Also PEGs can be stripped out of benzene, acetone, and several other organic solvents by adding diethyl ether! One of the referenced articles used PEGs to complex with an organic acid, with an imine attached and PEGs also served as a PTC for the base for an imine alkylation.

R-CH(NPh2)-CO2-PEG + KOH + R'X --> R-CH(NPh2)(R')-CO2-PEG

All in all the articles were very interesting. They talked a lot about the ability of the PEGs to chelate the alkalli metal ions very much the same way that he crown ethers disolve the alkali metals. (Apparently the larger ions are chelated better) I am begining to think that Birch dream with brake fuild really will work dispite the fact that I have never heard any thing back about that muse of mine that I have repeatly interjected.

Post by: sunlight on January 30, 2001, 10:52:00 AM: Sorry for the delay in answering you, but I was confused, I'm not living in Tucson or in any place of USA; I live in the old Europe. And I like it.
I'll see if I can find synth comm in the nearest university of home, I don't remmeber to see it before, but I'm not sure.

Post by: sunlight on January 30, 2001, 05:59:00 PM: I've been in the university library, and as I thought, synth om is not there, unfortunately. So I would thank to see that references posted in the Hive.
Thanks bees.
Title: Dumb question
Post by: Antibody2 on February 01, 2001, 04:16:00 PM: I'm no chemist or I probably wouldn't need to ask.

What does "Synth Commun" stand for.

Synthesis Communiqué? The computer just gives me a blank look when I bang in "Synth Commun".

Just gone.
