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.
