Iridium and rhodium complexes containing dichalcogenoimidodiphosphinato ligands

摘要: Abstract Treatment of [MCl(CO)(PPh3)2] with K[N(R2PQ)2] afforded [M{N(Ph2PQ)2}(CO)(PPh3)] (M = Ir, Rh; Q = S, Se). The IR C=O stretching frequencies for [M(CO)(PPh3){N(Ph2PQ)2}] were found to decrease in the order S > Se. [M(COD)Cl]2 K[N(Ph2PQ)2] [M(COD){N(Ph2PQ)2}] (COD = 1,5-cyclooctadiene; M = Ir, [Ir(ol)2Cl] K [ N ( Pr 2 i PQ ) ] Ir ol { } (ol = cyclooctene COE, C2H4; Oxidative addition [Ir(CO)(PPh3){N(Ph2PS)2}] and [Ir(COD){N(Ph2PS)2}] HCl [Ir(H)(Cl)(CO)(PPh3){N(Ph2PS)2}] trans-[Ir(H)(Cl)(COD){N(Ph2PS)2}], respectively. MeI [Ir(Me)(I)(CO)(PPh3){N(Ph2PS)2}]. [Ir(COE)2Cl]2 K[N(R2PO)2] [Ir(COE)2{N(Ph2PO)2}] that reacted MeOTf (OTf = triflate) give [Ir{N(Ph2PO)2}(COE)2(Me)(OTf)]. crystal structures [Ir(CO)(PPh3){N(Ph2PS)2}], [M(COD){N(Ph2PS)2}] Rh), PS (ol = COE, C2H4), have been determined.
