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. Treatment of [M(COD)Cl]₂ with K[N(Ph₂PQ)₂] afforded [M(COD){N(Ph₂PQ)₂}] (COD = 1,5-cyclooctadiene; M = Ir, Rh; Q = S, Se). Treatment of [Ir(ol)₂Cl] with K [ N ( Pr₂ⁱ PQ )₂ ] afforded [ Ir ( ol )₂ { N ( Pr₂ⁱ PQ )₂ } ]₂ (ol = cyclooctene COE, C₂H₄; Q = S, Se). Oxidative addition of [Ir(CO)(PPh₃){N(Ph₂PS)₂}] and [Ir(COD){N(Ph₂PS)₂}] with HCl afforded [Ir(H)(Cl)(CO)(PPh₃){N(Ph₂PS)₂}] and trans-[Ir(H)(Cl)(COD){N(Ph₂PS)₂}], respectively. Oxidative addition of [Ir(CO)(PPh₃){N(Ph₂PS)₂}] with MeI afforded [Ir(Me)(I)(CO)(PPh₃){N(Ph₂PS)₂}]. Treatment of [Ir(COE)₂Cl]₂ with K[N(R₂PO)₂] afforded [Ir(COE)₂{N(Ph₂PO)₂}] that reacted with MeOTf (OTf = triflate) to give [Ir{N(Ph₂PO)₂}(COE)₂(Me)(OTf)]. The crystal structures of [Ir(CO)(PPh₃){N(Ph₂PS)₂}], [M(COD){N(Ph₂PS)₂}] (M = Ir, Rh), [ Ir ( ol )₂ { N ( Pr₂ⁱ PS )₂ } ](ol = COE, C₂H₄), trans-[Ir(H)(Cl)(COD){N(Ph₂PS)₂}], and [Ir(COE)₂{N(Ph₂PO)₂}] have been determined.
