Simple Iron Catalyst for Terminal Alkene Epoxidation
Geraud Dubois, Andrew Murphy, and T. Daniel P. Stack*
Organic Letters, 2003, Vol 5, No. 14 Page 2469-2472
pubs.acs.org/doi/abs/10.1021/ol0347085
Quote
A mu-oxo-iron(III) dimer, [((phen)2(H2O)FeIII)2(?-O)](ClO4)4, is an efficient epoxidation catalyst for a wide range of alkenes, including terminal alkenes, using peracetic acid as the oxidant. Low catalyst loadings, in situ catalyst preparation from common reagents, fast reaction times (<5 min at 0 °C), and enhanced reaction performance at high substrate concentrations combine to create a temporally and synthetically efficient procedure for alkene epoxidation.
100% conversion from both cis & trans beta methyl styrene (96% isolated yields).  Epoxidation with performic/peracetic acid usually leads to relatively high yields of the glycol ester, but this cuts the reaction time down by an order of magnitude.

SO, because i not found any reference exchange thread, im starting one.

A new member doesn't have access to the forum in which that thread is in until they have the required number of posts   ;)  The article you requested is published in a rather obscure journal that's not easily available online but the text of it is in the attached archive :P  On the other hand the article that's attached:

Kinetics of Oxidative Decarboxylation of 3,4-Methylenedioxymandelic Acid to Piperonal with Dilute Nitric Acid

Hongjuan Xi†‡, Zhixian Gao*† and Jianguo Wang†
Institute of Coal Chemistry, Chinese Academy of Sciences, Taiyuan 030001, People’s Republic of China, and Graduate University of the Chinese Academy of Sciences, Beijing 100039, People’s Republic of China
Ind. Eng. Chem. Res., 2009, 48 (23), pp 10425–10430
DOI: 10.1021/ie900961r

is more easily found and discusses the subject you're interested in  ;D  Your request made via pm isn't possible  :-X  Once you participate in this forum for a little while you'll have access to the references section  8)

These two articles are among the most exciting Assyl has ever read... oxycodone analogs easily made from oxycodone itself in a single step, which have potencies ranging from  100-24,000x morphine, with far less dangerous respiratory depression, less unpleasant ones such as constipation, physical coordination problems, sedation, and physical withdrawal, and yet far greater anxiolytic and positive emotive effects. Why haven't they made it to market? Probably because they're too good.

These are some old articles from the Journal of American Chemical Education. They are typically lab based demonstrations for the preparation of useful compounds

Preparation of methylamine

A chamber sulphuric acid plant for lecture demonstration

laboratory preparation of hydrofluoric acid

Preparation of constant boiling HBr

Preparation of acetamide

Oxidation of ammonia to nitric acid

methylamine from methanol and ammonia

Designer drugs: a medicinal chemistry perspective
F. Ivy Carroll, Anita H. Lewin, S. Wayne Mascarella, Herbert H. Seltzman,
and P. Anantha Reddy
Ann. N.Y. Acad. Sci.
xxxx (2011) 1–21 ?c 2011
DOI: 10.1111/j.1749-6632.2011.06199.x


Abstract
There are numerous medicinal chemistry reports in the literature describing the pharmacological properties of thousands of narcotics, stimulants, hallucinogens, sedative-hypnotic drugs, cannabinoids, and other psychoactive substances as well as synthetic methods for their preparations. This information, while essential for the advancement of science, has been used by clandestine chemists to manufacture and market an endless variety of analogs of so-called designer drugs. In this review, we describe how clandestine chemists used the principles of medicinal chemistry to design molecules, referred to as designer drugs, that elicit the effects of opioids, amphetamine and analogs, cannabinoids, and phencyclidine analogs while circumventing the law.

Keywords: controlled substances, designer drugs, medicinal chemistry, opioids, analgesics, amphetamines, cannabinoids, PCP, stimulants, hallucinogens
