Abstract
Synthesis of Triafulvalene Precursors by ‘Carbene‐Dimerization’ of 1‐Halogeno‐1‐lithiocyclopropanesBi(cyclopropylidenes) 7a, 7c, and 7e are available in a simple one‐pot reaction by treating 1,1‐dibromocyclo‐propanes 5 at −95° with BuLi and CuCl2. Attempts towards triafulvalene precursors with good leaving groups are reported. The most promising attempt makes use of 2,2′‐bis(phenylthio)‐3,3′‐bis(trimethylsilyl)‐1,1′‐bi(cyclopropylidene) (7c) which has been oxidized to give the bis(phenylsulfonyl) derivative 7g. So far, F−‐induced elimination experiments with 7g failed.
