摘要：

Nucleophilic addition of methanol to nonactivated alkynes is catalyzed by platinum phosphine complexes derived from PtCl2(ligand) [ligand = 2PPh(3), 2PPh(2)Me, diphos, dppt (1,5-bis(diphenylphosphino)pentane)] and a silver salt [AgPF6 or AgOTf (silver trifluoromethanesulfonate)] producing Ketones in high yields. The catalytic activity is influenced by the phosphine ligand as well as by the anion and the ratio of the dichloroplatinum complex: to the silver salt.
