    C−H Activation Induced by Water. Monocyclometalated to Dicyclometalated:  C∧N∧C Tridentate Platinum Complexes
    摘要:
    Metalation of 2,6-diphenylpyridine (1) by potassium tetrachloroplatinate in acetic acid gives a monocyclometalated chloride-bridged dimer 4. This dimer is split with CO to give a kinetic product st with the incoming CO trans to the orthometalated carbon. The kinetic product of cleavage is shown to be 16 kJ mol(-1) higher in energy than the thermodynamic product 9c, which has the CO trans to the pyridine nitrogen. The isomerization of 9t to 9c is shown not to take place via an associative mechanism and, with analogue 11, is effectively suppressed when excess chloride is added, implying that it takes place via a chloride dissociation. The monocyclometalated 9 undergoes a second cyclometalation to give the C boolean AND N boolean AND C dicyclometalated complex 15 in high yield. This second cyclometalation is brought about by the simple expedient of adding water to the monocyclometalated precursor. The addition of water is rationalized on the basis of needing to ionize the HCl byproduct of the reaction. Using a substituted pyridine (5) analogous chemistry is observed. Single-crystal X-ray structures of one of the intermediates (6) and one of the final products (15) have been solved. Density functional theory calculations are used to rationalize the isomerizations of the monocyclometalated intermediates and the need to ionize HCl in the second cyclometalation.

    The novel long-range “cis-spanning” PP ligand LPP coordinates AuCl and Pt(CNC) in a highly selective manner. Subsequent halide abstraction gives rise to the formation of a Au−Pt bond. While the “cis-spanning” PN ligand LPN does not allow for the generation of heterodinuclear complexes with a metal–metal bond, its potential to serve as a ditopic ligand has been shown in the present work.
