Abstract

Diazomethane and its derivatives react with aldehydes and ketones usually under very mild conditions to yield a variety of interesting and often useful products. The Reaction">The reaction is most often carried out by either allowing the carbonyl compound to react with an ethereal solution of the diazomethane derivative with or without the addition of a catalyst, or by treating a methanol solution of the carbonyl compound with a nitrosoalkylurethane in the presence of a base, Only the reactions of diazomethane and its alkyl and aryl derivatives are discussed in detail.
