Evidence for LiBr‐Assisted Generation of a Silylene from a 1,2‐Diaryl‐1,2‐dibromodisilene

Abstract

Instant silylene! LiBr assists the dissociation of 1,2-diaryl-1,2-dibromodisilenes. Reactions with various trapping agents gave products identical to those from corresponding reactions with aryl bromosilylenes. The reaction provides a method for the in situ generation of silylenes under mild conditions, and the reaction rate is increased by the addition of LiBr.
