Primary, secondary and tertiary vinylstannanes 2a-2f are synthesized by reduction of the corresponding chloro(vinyl)stannanes. They are characterized by their spectral data (IR, NMR (Sn-119, C-13, H-1) spectroscopy and mass spectrometry). The Sn-119 chemical shifts and (1)J(SnH) and (1)J(SnC) of vinylstannanes are compared with the data reported for the corresponding alkyl- and aryl-stannanes. Compounds 2 decompose slowly at room temperature in benzene (tau(1/2) 1-3 days). The formation of divinylchlorostannane and the use of trivinylstannane as a reducing agent are also reported.
