Simple approach to 1-alkyl-2-isopropylhydrazines

Ditosylates of 1-alkyl-2-isopropylhydrazines were prepared by N-alkylation of t-butyl isopropylidenecarbazate (2) followed by reduction of N-alkyl-t-butyl isopropylidenecarbazate (3) with lithium aluminum hydride in boiling tetrahydrofuran. The removal of

A new route to monoalkylhydrazines

Electrophilic amination of primary amines with N-(diethoxyphosphoryl)-O-(p-nitrophenylsulfonyl)-hydroxylamine 1, followed by dephosphorylation of the phosphorohydrazidate 2 with p-toluenesulfonic acid monohydrate in ethanol, represents a novel approach to monoalkylhydrazines.

A Simple Alkylative Approach to Monoalkylhydrazines

Phase-transfer-catalyzed N-alkylation of acetone N-(diethoxyphosphoryl)hydrazone, followed by deprotection with p-toluenesulfonic acid monohydrate in ethanol, represents a novel and convenient synthesis of monoalkylhydrazines.
