摘要：
2,4-Diaryl- and 2,4-diferrocenyl-1,3-dithiaphosphetane disulfide dimers (1a-1c) react with a variety of alcohols, silanols and trialkylsilylalcohols to form dithiophosphonic acids in a facile manner. Their corresponding salts react with chlorogold(I) complexes to produce the first dinuclear gold(I) dithiophosphonate complexes of the type [AuS2PR( OR')](2) (R = Ph, R' = Et (2); R = p-C6H4OMe, R' = SiPh3) (3)) in high yield ( > 70%). The dinuclear gold(I) complexes react with dppm (Ph2PCH2PPh2) or dppa (Ph2PNHPPh2) to form new heterobridged dinuclear gold(I) complexes of the type [Au-2(dppm)S2P(O)R] (R = Ph (4)). Moreover, 1a-1c react with Au-2(dppm)Cl-2 to form new heterobridged trithiophosphonate gold(I) complexes of the type [Au-2(dppm)S2P(S)R] (R = ferrocenyl (5)). (C) 1998 Elsevier Science S.A.
