Abstract

Multinuclear nmr (1H, 77Se, 111/113Cd, 119Sn, 199Hg, as appropriate) has been used to study Y--EPh-exchange in Me2CO or MeCN between R n M'Y (R n M'= Ph3Sn or MeHg; Y= Cl, Br, I, NCO, or NCS) and the adamantane-like anions [(μ-EPh) 6 (MEPh) 4] 2-(E= S, M= Zn, Cd, or Co; E= Se, M= Zn or Cd), as their tetraalkylammonium salts. Quantitative terminal substitution of the clusters occurs in most cases, giving [(μ-EPh) 6 (MEPh) 4-x (MY) x] 2-(x ...
