Abstract:
A Group 3 through 11 (IUPAC) transition metal or lanthanide metal complex of a ligand of the formula (I) wherein:Z is nitrogen and Q is phosphorous, or Z is oxygen and Q is phosphorous, Z is oxygen and Q is nitrogen; provided that:when Q is phosphorous and Z is nitrogen: R1 and R2 are each independently hydrocarbyl, silyl, or substituted hydrocarbyl having an Es of about âˆ’0.90 or less; R3, R4, R5, and R6 are each independently hydrogen, hydrocarbyl, a functional group, or substituted hydrocarbyl; R7 is hydrogen, hydrocarbyl, substituted hydrocarbyl or silyl; and R8 is hydrocarbyl, substituted hydrocarbyl, or silyl; provided that any two of R3, R4, R5a, R6, R7 and R8 vicinal or geminal to one another together may form a ring; when Q is phosphorous and Z is oxygen: R1 and R2 are each independently hydrocarbyl, silyl, or substituted hydrocarbyl having an Es of about âˆ’0.90 or less; R3 and R4 are each independently hydrogen, hydrocarbyl, a functional group, or substituted hydrocarbyl; R5 and R7 taken together form a double bond; R8 is not present; and R6 is â€”OR9, â€”NR10R11, hydrocarbyl or substituted hydrocarbyl, wherein R9 is hydrocarbyl or substituted hydrocarbyl, and R10 and R11 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl; and provided that any two of R3, R4, and R6 vicinal or geminal to one another may form a ring; or R1 and R2 are each independently hydrocarbyl, silyl, or substituted hydrocarbyl having an Es of about âˆ’0.90 or less; R3, R4, R5 and R6 are each independently hydrogen, hydrocarbyl, a functional group, or substituted hydrocarbyl; R7 is hydrocarbyl, silyl, or substituted hydrocarbyl; and R8 is not present; and provided that any two of R3, R4, R5, R6, and R7 vicinal or geminal to one another may form a ring; when Q is nitrogen: R1 is hydrocarbyl, silyl, or substituted hydrocarbyl having an Es of about âˆ’0.90 or less; R2 and R3 are each independently hydrogen, hydrocarbyl, a functional group, or substituted hydrocarbyl, or taken together form a double bond; R4 is hydrogen, hydrocarbyl, a functional group, or substituted hydrocarbyl; Z is oxygen; R6 and R7 taken together form a double bond; R8 is not present; R5 is â€”OR12, â€”R13 or â€”NR14R15, wherein R12 and R13 are each independently hydrocarbyl or substituted hydrocarbyl, and R14 and R15 are each hydrogen, hydrocarbyl or substituted hydrocarbyl; provided that when R2 and R3 taken together form an aromatic ring, R1 and R4 are not present; and further provided that any two of R2, R3, R4 and R5 vicinal or germinal to one another taken together may form a ring.
