Highly efficient chemo- and regioselective silylation of –OH groups and cyanosilylation of aldehydes promoted by TiCl2(OTf)–SiO2 as a new recyclable catalyst
چکیده انگلیسی

TiCl2(OTf)–SiO2 as an easy handling recyclable catalyst was applied for trimethylsilylation of diethyl α-hydroxyphosphonates, alcohols and phenols with high selectivity using HMDS as a silylating agent. Cyanotrimethylsilyl ethers were also obtained in excellent yields from treatment of aldehydes with TMSCN in the presence of this catalyst.

TiCl2(OTf)–SiO2 as a non-hygroscopic, easy handling recyclable catalyst was applied for trimethylsilylation of diethyl α-hydroxyphosphonates, alcohols and phenols with high selectivity using HMDS as a silylating agent. Cyanotrimethylsilyl ethers were also obtained in excellent yields from treatment of aldehydes with TMSCN in the presence of this catalyst.Figure optionsDownload as PowerPoint slide
