Description

Application

Allyltrimethoxysilane is an allylating reagent that can be used for the allylation of carbonyl compounds such as aldehydes, ketones, and imines. Homoallylic alcohols and amines are obtained via the C-C bond forming reaction. It can also be used to synthesize homoallylic α-branched amines from aromatic and aliphatic aldehyde hydrazones, and ketone hydrazones.
