                                    Methylplatinum triflate coordinated with 1,2-diphenyl-3,4-bis[(2,4,6-tri-t-butylphenyl)phosphinidene]cyclobutene serves as a highly selective catalyst for dehydrogenative silylation of ketones with HSiMe2Ph in the presence of pyridine as a co-catalyst, giving silyl enol ethers in high yields.
