Abstract

The new Class 2 gold-boron compounds [5,6-μ-(AuPR3)-nido-B10H13] (1a; R = cyclo-C6H11; 1b, R = C6H4Me-2) have been prepared by the reaction between [AuMe(PR3)] and B10H14 in CH2Cl2. Compound (1a) is also afforded by reaction between [AuCl{P(C6H11)3}] and [B10H13]-. The exact mechanism of the first reaction is unclear, but probably proceeds via sequential oxidative addition and reductive elimination. Crystallographic analyses of compounds (1) show the expected decaborane-like geometry. There is some evidence of an intramolecular interaction between Au and the B(9)-H-B(10) bridge system. A thorough n.m.r. study of (1b) was undertaken, including an 11B(COSY) experiment which allowed almost complete assignment of the ten inequivalent B atoms in the molecule.
