Thermal rearrangement of allylic amine-imides and related topics
Abstract
Deuterium reduction (Pd–BaSO4) of NN-dimethylpropargylammoniobenzamidate to N-(2,3-dideuterioallyl)dimethylammoniobenzamidate and thermal rearrangement of the latter to N-(1,2-dideuterioallyl)-N′N′-dimethylbenzohydrazide validates a concerted [3,2] rearrangement for unsubstituted allyl groups in this series. Thermolysis of related hydrazinium halides gives the dialkylhydrazides.
