The synthesis of RAuPPh3 (R = aryl) from ClAuPPh3 and Grignard RM reagents (M = Li or MgX) is described. New (vinylphenyl)gold(I) and other arylgold(I) complexes were characterized by H-1, C-13, P-31, F-19 NMR, melting point determination, and X-ray diffraction. Crystallographic studies of sorne organogold(I) complexes indicate in aurophilic Au(I)... Au(I) attraction. (c) 2005 Elsevier B.V. All rights reserved.
