Bi(cyclopropylidenes) 7a, 7c, and 7e are available in a simple one-pot reaction by treating 1,1-dibromocyclopropanes 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.
