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.
与 1,2-二苯基-3,4-双[(2,4,6-三叔丁基苯基)膦]环丁烯配位的三氟甲磺酸甲酯铂作为一种高选择性催化剂,用于在吡啶存在下用 HSiMe2Ph 对酮进行脱氢甲硅烷基化作为助催化剂,以高产率得到甲硅烷基烯醇醚。
