Abstract:
1. A composition comprising: (1) a metal selected from nickel or palladium connected to a ligand comprising 1,4-diazabutadiene: (a) having a phenyl ring connected to the 1 position of the diazabutadiene where the phenyl ring is connected at the 3, 4 or 5 position to at least one hydrocarbyl group having at least three carbon atoms, and (b) having a phenyl ring connected to the 4 position of the diazabutadiene where the phenyl ring is connected at the 3, 4 or 5 position to at least one hydrocarbyl group having at least three carbon atoms, and (c) where the 2 and 6 positions of both phenyl rings are connected to hydrogen radicals, and (d) where the 2 and 3 positions of the diazabutadiene are, each independently, connected to hydrogen or a hydrocarbyl group; and (2) an abstractable ligand connected to the metal, that does not contain sulfur atoms.
