 Title    Austauschreaktionen von Tri-/i -butylethinylstannan mit Zinntetrachlorid und Zinntetrabromid -Anwendung der 119 Sn-NMR Spektroskopie Exchange Reactions between Tri-n-butyl Ethynyl Stannane and Tintetrachloride and Tintetrabromide -Application of U9 Sn NMR Spectroscopy  
 Abstract    The formation of ethynyl stannanes Xra Sn(C = C-H)4 -n (X = Cl, Br; n — 0—3) via ex-change reactions between tri-n-butvl ethynyl stannane and SnX4 is readily monitored by 119 Sn NMR spectroscopy. Advantages of il9 Sn NMR as compared with iH or 13 C NMR are discussed. The 119 Sn and 13 C NMR parameters (<5 119 Sn, <5 13 C, W (119 Sn 13 C), WpCiH)) for these reaction mixtures are reported. Tri-n-butyl ethynyl stannane and bis(tri-n-butyl-stannyl)ethyne are both obtained from the reaction of tri-n-butylstannylchloride with L^Ca in hexane in the presence of excess ethyne.
