摘要：
A new ferrocenyl-bisphosphine, 1,1'-bis(dipyrrolylphosphino)ferrocene (dpypf) (1) was synthesized by the reaction of [Fe(C5H4PCl2)(2)] with lithiated pyrrole at -78 degrees C. The bis(selenide) [Fe {C5H4P(Se)(NC4H4)(2)}(2)] (2) and tetracarbonyl derivatives [M(CO)(4)(dpypf)] (3, M = Mo; 4, M = W) were synthesized by reacting 1 with elemental selenium and [M(C5H11N)(2)(CO)(4)] (M = Mo, W), respectively. The reaction of 1 with [Ru(eta(6)-p-cymene)Cl-2](2) in 1:2 molar ratio yielded the dinuclear complex [(Ru(976-pcymene)02)2(ii-dPYPOl (5), whereas the reaction with [CpRu(PPh3)(2)Cl] in 1:1 molar ratio produced a chelate complex [CpRuCl(dpypf)] (6). The reactions of 1 with M(COD)Cl-2 (M = Pd, Pt) yielded chelate complexes, [MCl2(dpypf)] (7, M = Pd, 8, M = Pt). Treatment of 1 with AgOTf in 1:1 molar ratio gave a dinuclear complex [Ag(mu-OTf)(dpypf)]2 (9). Gold complex [Au2Cl2(A-dpypf)] (10) was obtained by reacting 1 with two equivalents of [AuCl(SMe2)]. Crystal structures of 2-4 and 6-10 were established by single-crystal X-ray diffraction studies. (C) 2016 Elsevier B.V. All rights reserved.
