The carbenoids 2 undergo at ‐110°C a bromine/lithium exchange reaction with 1,1‐dibromo alkanes. This leads to partial equilibration of the carbenoids 2 during their generation from the 1,1‐dibromo compound 1 . In the absence of the precursor 1 , the carbenoids 2 have been found to be configurationally stable at ‐110°C.
