Oxidation of monomeric N,N′-dilithium N,N′-bis(di-tert-butylmethylsilyl)hydraz ide to the diazene

Abstract

The reaction between the bis(silyl)hydrazine RNHNHR and butyllithium in thf affords the first monomeric dilithium bis(silyl)hydrazide RNLiNLiR·3thf 1 (R = SiBu^t₂Me) and the crystal structure of 1 is presented; the thermally stable bis(silyl)diazene RN=NR 2 (R = SiBu^t₂Me) is formed in the reaction between 1 and Br₂.
