摘要：
The stereoelectronic properties of the PR2(2,6-Me2C6H3) (R=Ph, Cy) ligand can be used to stabilize an unprecedented class of 14-electron platinum(II) complexes. The X-ray analysis of the cyclometalated cyclohexyl derivative reveals an agostic interaction between the Pt center and an o-methyl moiety (see picture). The fast and reversible formation of three-coordinate platinum-hydrido complexes occurs by reaction with H2, and is achieved through the cleavage of a platinum-carbon bond.
