We believe that the mechanism of these reactions consists of the formation of the intermediates A, by nucleophilic attack of DMSO on the trimethylsilylchloride and B, by nucleophilic attach of oxime on the intermediate A, which undergoes elimination to give the corresponding nitriles (Scheme 2).
The differences in formaldehyde could be due to the breakdown of the oxime derivative.
The lack of oxime effect was postulated to be due the type of organophosphate compound (dimethyl vs.
A Tc-99m hexamethylpropylene amine oxime (HMPAO) leukocyte scan was performed on the 8th day of symptoms, the results of which were normal.
Select C(alpha), O-oximes, such as 3,4-dimethoxyacetophenone or 3,4- dimethylacetophenone oxime, were dilithiated in excess LDA, followed by condensation with ethyl oxanilates to afford C-acylated intermediates that can be cyclized directly with dilute hydrochloric acid/THF, or isolated and separately acid-cyclized to 5- isoxazolecarboxamides using methanesulfonic acid and a water trap.
Both phenols exclusively form quinone or quinone oxime products in neutral or acidic conditions.

Oligomeric alkene monoamine for instance was prepared by epoxidizing an oligomeric alkene to form an oligomeric alkene aldehyde and an oligomeric alkene monoamine, which is obtained over oxime.
