Abstract

The C–H activation of the methyl group of tetramethylthiourea by cis-[PtL2(NO3)2] (L = phosphine or N-heterocyclic carbene) has been investigated as a function of the ligand L. The presence of an electron-withdrawing group on the tertiary phosphine was found to promote the process. Moreover, when an excess of nitrate anion is present in the reaction mixture, the rate of C–H bond activation is retarded, suggesting the key role of an unsaturated tri-coordinate PtII species as intermediate.
