摘要
Bis(2,4,6-triisopropylphenyl)(fluorenylidene)stannene-diethyl ether (1a), a new stable compound with a formal tin-carbon double bond, has been synthesized by dehydrofluorination of the corresponding fluoro-stannane with tert-butyllithium; it has been characterized by NMR (delta(Sn-119) + 288 ppm, delta(C-13) + 133.85 ppm) and UV spectroscopy (lambda(max) 542 nm) and by electrophilic addition reactions to the tin-carbon unsaturation,
