with CF3I, allyl- and benzyl-halides takes a different course giving organic coupling products and [RhX(CO)(PPh3)2]. The THF solvate complex also causes coupling of gem-dihalides, and dehalogenation of vic-dihalides to produce alkenes. Possible mechanisms for these reactions are discussed.
gave no addition product, but did 9-chlorofluorene in 85–89% yield. The same reaction in carbontetrachloride gave 9,9′-dichloro-9,9′-bifluorenyl in 48% yield. Thus fluorenylidene has strong abstraction character. These chemical results suggest that fluorenylidene and 2,7-dibromofluorenylidene react in triplet state. Furthermore the ground states of these carbenes were confirmed to be triplet by ESR spectra
