Abstract
A composition comprising a perfluoro-N2-phosphinylamidine chromium salt complex having Structure PFAHNPACr I: wherein Rf1 is a substituted phenyl group comprising alkyl groups at the 2 and 6 positions and at least one fluoro group or perfluoroalkyl group at the 3, 4, and/or 5 positions, R2 is a C1 to C30 organyl group, R4 and R5 are each independently a C1 to C30 organyl group, and CrXp is a chromium salt where X is a monoanion, and p is an integer from 2 to 6.
