Résumé
Treatment of 1,2-diphosphinobenzene with [Au(C6F 5)3(tht)] leads to the diphosphane derivative [{Au-(C 6F5)3}(1,2-PH2C6H 4PH2)] (1), which further reacts with other pentafluorophenylgold(m) reagents in the presence of acetylacetonate as deprotonating agent to afford phosphane-phosphide complexes. The noncyclic PPN[(Au(C6F5)3,}2(1,2-PHC 6H4PH2)] (2; PPN =bis(triphenyl-phosphine) iminium) has been shown to be a useful starting material for the synthesis of higher nuclearity cyclic or noncyclic diphosphide or even diphosphodiide derivatives through similar reactions. The crystal structures of the trinuclear anionic NBu4[{Au(C6F5)3)(1,2- PHC6H4PH)-{(Au(C6F5) 2Cl}{μ-Au(C6F5)2)] (3) and the hexanuclear [{Au(C6F5)3)1,2-PC6H 4P){Au(C6F5)3}{μ-M(dppe)M) 2} (M = Au (12), Ag (13)) have been established by X-ray diffraction methods, the last complexes having a bicyclic ring containing three intramolecular interactions between the M1 centres. © 2006 Wiley-VCH Verlag GmbH & Co.
