Exchange Reactions between Tri-n-butyl Ethynyl Stannane and Tintetrachloride and Tintetrabromide - Application of 119Sn NMR Spectroscopy

The formation of ethynyl stannanes XnSn(CC-H)(4-n) (X = Cl, Br; n = 0-3) via exchange reactions between tri-n-butyl ethynyl stannane and SnX4 is readily monitored by 119Sn NMR spectroscopy.Advantages of 119Sn NMR as compared with 1H or 13C NMR are discussed.The 119Sn and 13C NMR parameters (δ119Sn, δ13C, 1,2J(119Sn13C), 1,2J(13C1H)) for these reaction mixtures are reported.Tri-n-butyl ethynyl stannane and bis(tri-n-butylstannyl)ethyne are both obtained from the reaction of tri-n-butylstannylchloride with Li2C2 in hexane in the presence of excess ethyne. - Key words: Exchange Reactions, Ethynyl Stannanes, 119Sn NMR Spectra, 13C NMR Spectra
