Abstract:
A polymerization reaction employing a composition comprising:(1) a compound characterized by the general formula: â€ƒwherein each R1, R2, and R3 is independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxy, aryloxy, silyl, boryl, phosphino, amino, thio, seleno, and combinations thereof; optionally, R1 and R2 are joined together in a ring structure and/or R1 or R2 is joined together with X in a ring structure; also optionally, R3 and X are joined in a ring structure; E is selected from the group consisting of nitrogen and phosphorus (provided however that when E is N, X is not a benzylic group bound to N through the CH2 of the benzylic group); and X is a covalent bridging moiety; (2) a metal precursor are characterized by the formula: M(L)n; where M is a transition metal selected from the group consisting of Groups 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 of the Periodic Table of Elements; L is independently each occurrence, a ligand; and n is 0, 1, 2, 3, 4, 5 or 6; â€ƒprovided however that when E is P and R3 is H, then X cannot be R4R5Câ€”CR6R7 or R4C&boxH;CR5, wherein R4-R7 are independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxy, aryloxy, silyl, boryl, phosphino, amino, thio, seleno, and combinations thereof; and, (3) optionally, at least one activator.
