Article abstract of DOI:10.1021/om00044a005

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 (δ(¹¹⁹Sn) + 288 ppm, δ(¹³C) +133.85 ppm) and UV spectroscopy (λ_max 542 nm) and by electrophilic addition reactions to the tin-carbon unsaturation.
