Abstract

Isomerization of phenyl-substituted propargylplatinum (II) complex, trans-Pt (CH2C CPh)(Cl)(PPh3) 2 (1) to allenyl complex, trans-Pt (CPh C CH2)(Cl)(PPh3) 2 (2) was found to be catalyzed by zerovalent complex Pd (PPh3) 4. The reaction was proposed to proceed through the transfer of the propargyl/allenyl ligand both from Pt (II) to Pd (0) and Pd (II) to Pt (0). The former transfer, which seemingly has a thermodynamic disadvantage, has ...
