A stable compound with a formal tin-carbon double bond: the bis(2,4,6-triisopropylphenyl)(fluorenylidene)stannene

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, de...
