Abstract:
A composition comprising an organic solvent solution of an Ir(I) reagent, wherein said Ir(I) reagent is selected from the group consisting of:Lewis base stabilized Ir(I) &bgr;-diketonates of formula I: â€ƒwherein R and Râ€² may be alike or different and may be H, aryl, perfluoroaryl, C1-C6 alkyl, or C1-C6 perfluoroalkyl, and L is a coordinating Lewis base; and Lewis base stabilized Ir(I) &bgr;-ketoiminates of formula II: â€ƒwherein R, Râ€², and Râ€³ are the same or different, and are independently selected from the group consisting of H, aryl, perfluoroaryl, C1-C6 alkyl, or C1-C6 perfluoroalkyl, and L is a coordinating Lewis base selected from the group consisting of alkene, diene, cycloalkene, cyclodiene, cyclooctatetraene, alkyne, substituted alkyne (symmetrical or asymmetrical), amine, diamine, triamine, tetraamine, ether, tetrahydrofuran, glyme, diglyme, triglyme, tetraglyme, phosphine, carbonyl, dialkyl sulfide, vinyltrimethylsilane, and allyltrimethylsilane.
