    Bayer villiger oxidation solvent dilution question.

    A research paper oxidizes some alpha beta unsaturated ketones to vinyl acetates, and the amount of solvent used is alot due to them doing it on such a small scale. here is the method; What ratio would you imagine would be appropriate with regards to ketone to dimethyl formamide in scaling this...

    Methaqualone (Quaalude) synthesis

    This thread is inaccurate the first image at the top of the page is the molecule Alprazolam, I should have been more specific but the post I made above was that in the first step of the reaction 2,2' dimethylbenzanilide isn't produced instead 2-amino-N-(o-tolyl)benzamide is produced (the amino...

    What is the most popular method of reduction in large scale methamphetamine production?

    Mexican cartels produce large quantities of methamphetamine, They permit journalists to tour their labs and even interview them, the journalists never have the sense to ask them questions pretaining to choice of reagent for reduction. Does anyone know?

    Demethylation of N methyl pyrrolidone.

    Does anyone here know if the Von Braun reaction where tertiary amines are dealkylated to cyanamides is applicable to tertiary amides. ie; could I react N methyl pyrrolidone a tertiary amide with cyanogen bromide and get 2-oxopyrrolidine-1-carbonitrile, the N cyano derivative. (For making gamma...
