Abstract

The reaction of diorganotin sulfides, cyclo-(R2SnS) n (R= Me, n-Bu; n= 3; R= t-Bu; n= 2) with the corresponding diorganotin dichlorides, R2SnCl2, provided the tetraorganodistannathianes,(R2ClSn) 2S (1, R= Me; 2, R= n-Bu; 3, R= t-Bu). 1H-, 13C-, and 119Sn-NMR studies indicate that these compounds are kinetically labile and in equilibrium with the starting materials. Addition of equimolar amounts of [(Ph3P) 2N] Cl to the reaction ...
