Iridium complexes of orthometalated triaryl phosphites: Synthesis, structure, reactivity, and use as imine hydrogenation catalysts

Di-orthometalated iridium complexes of triaryl phosphites have been prepared and characterized. The synthesis of the triphenyl phosphite derivative [IrH(cod){P(OC6H4)2-(OC6H 5)}], 3, requires a circuitous route by treatment of [IrCl(cod){P(OPh)3}] with methyllithium and then methanol. However, with the hindered phosphites P(OAr)3 (Ar = C6H4-2-tBu or C6H3-2,4-tBu2) the di-orthometalated species 5a,b are readily obtained by reaction of the phosphite with [{Ir(μ-OMe)(cod)}2] or [Ir(cod)(py)2][PF6]. The mechanisms of these reactions have been investigated and are different. Both 5a and 5b are catalysts for imine hydrogenation. The complexes [IrH5{P(OAr)3}2] have been isolated from hydrogenation reactions and synthesized independently.
