Abstract

Additions of PhEH (E = O, S), PhEH2 (E = N, P), MesPH2, and Ph2PH to Cp2Zr(PR*)-(PMe3) (2) provide a facile route to complexes of the form Cp2Zr(PHR*)(ER) (R* = 2,4,6-t-Bu-C6H2; ER = OPh (3), SPh (4), NHPh (5), PHPh (6), PHMes (7), PPh2 (8)). Variabletemperature NMR studies are consistent with facile metal-mediated inversion at phosphorus as well as rapid rotation about the Zr-E bonds at room temperature.
