Five-coordinate platinum(IV) alkyl complexes bearing sterically non-demanding pyridylpyrrolide ligands, (LX)PtMe3 [LX = 3,5-di-tert-butyl-2-(2-pyridyl)pyrroiide (3a) and 3,5-diphenyl-2-(2-pyridyl) pyrrolide (3b)] have been prepared. An X-ray structure of 3a establishes that it is a five-coordinate PtIV complex with a square-pyramidal geometry. Thermolysis of 3a or 3b in C6D6 with ethylene results in reductive elimination of ethane (C2H6) and methane (CH4 and CH3D) and the formation of cyclometalated platinum(II) ethylene complexes 4a or 4b, respectively. Results of kinetic investigations of the reaction of 3b are consistent with a mechanism of direct C-C reductive elimination from the five-coordinate PtIV compound. Thermolysis of 3a in C6D6 with no ethylene present forms a novel dinuclear complex (5-d6).
