The new Class of 2 gold-boron compounds (1a; R=cyclo-C6H11; 1b, R=C6H4Me-2) have been prepared by the reaction between and B10H14 in CH2Cl2.Compound (1a) is also afforded by reaction between > and (1-).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 decarborane-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.

Two phosphane-gold(i) functions (with tri(para-tolyl)- or tri-n-butylphosphane) were attached to a 1,8-diethynylanthracene backbone. The ligand size prevents direct interaction between the gold atoms, but the initial products rearrange to form macrocyclic
Photosensitizer-Free, Gold-Catalyzed C–C Cross-Coupling of Boronic Acids and Diazonium Salts Enabled by Visible Light

The first photosensitizer-free visible light-driven, gold-catalyzed C–C cross-couplings of arylboronic acids and aryldiazonium salts are reported. The reactions can be conducted under very mild conditions, using a catalytic amount of tris(4-trifluoromethyl)phosphinegold(I) chloride [(4-CF3-C6H4)3PAuCl] with methanol as the solvent allowing an alternative access to a variety of substituted biaryls in moderate to excellent yields with broad functional group tolerance. (Figure presented.).
