Abstract
The preparation of Lewis-acid–base adducts of the type R3SbHgX2(R = phenyl, o- and p-tolyl; X = Cl, Br, and I) are reported. Reaction of the o-tolylstibine with HgCl2 in benzene yields Hg2Cl2 and R3SbCl2. In tetrahydrofuran the reaction products are R2SbCl and RHgCl. These results are interpreted in terms of a scrambling occurring via a five-co-ordinate antimony labile intermediate formed via oxidative addition of the stibine by HgCl2. Reaction of R3Bi with HgCl2 leads to the scrambling products R2BiCl and RHgCl.Keywords
