Abstract

The monomeric (NN)Pt(OH)₂ complex 1 (where NN = a bulky diimine ligand) undergoes sequential C-H bond addition across the Pt oxygen bonds at elevated temperatures in benzene to produce (NN)PtOH(C₆H ₅), 2, and (NN)Pt(C₆H₅)₂, 3, along with two equivalents of water. Several lines of evidence suggest that a slow homogeneous process is superseded by a faster catalysed pathway mediated by in situ produced elemental Pt(0) particles.
