ABSTRACT
Homobimetallic gold-selenolate complexes of the type [(Ph2R)PAuSe(C6H4)nSeAuP(Ph2R)] (3a, R = Et, n = 1; 3b, R = Et, n = 2; 5a, R = Ph, n = 1; 5b, R = Ph, n = 2) are obtained by the reaction of [Ph2RPAuCl] (1, R = Et; 4, R = Ph) with 0.5 equiv. of Me3SiSe(C6H4)nSeSiMe3 (2a, n = 1; 2b, n = 2) in good yield. Complex [(Pr3P)AuSe(C6H4)2SeAu(PPr3)] 7b can be prepared in a two-step synthesis procedure: treatment of [AuCl(SMe2)] 6 with 0.5 equiv. of Me3SiSe(C6H4)2SeSiMe3 2b gives [(Me2S)AuSe(C6H4)2SeAu(SMe2)], which further reacts with PPr3 to afford 7b. The new gold-selenolate complexes have been characterized by multinuclear NMR (1H, 31P, 77Se) and elemental analysis. The solid state structures of 3b, 5a, and 7b were determined by single X-ray structure analysis.
