摘要:
Additions of PhEH (E = O, S), PhEH(2) (E = N, P), MesPH(2), and Ph(2)PH to Cp(2)Zr(PR*)-(PMe(3)) (2) provide a facile route to complexes of the form Cp(2)Zr(PHR*)(ER) (R* = 2,4,6-t-Bu-C6H2; ER = OPh (3), SPh (4), NHPh (5), PHPh (6), PHMes (7), PPh(2) (8)). Variable-temperature NMR studies are consistent with facile metal-mediated inversion at phosphorus as well as rapid rotation about the Zr-E bonds at room temperature.
