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 (119Sn, 13C, 1H) spectroscopy and mass spectrometry. The 119Sn chemical shifts and 1JSnH and 1JSnC of vinylstannanes are compared with the data reported for the corresponding alkyl-and aryl-stannanes. Compounds 2 decompose slowly at room ...
