An efficient acid-catalyzed protection of alcohols as trityl ethers is described using triphenylmethanol in the presence of tris (pentafluorophenyl) borane (3mol%) in dichloromethane at room temperature. The chemoselectivity of this protocol is demonstrated by studying the tritylation of a primary alcohol in the presence of a secondary alcohol and also the mildness of this catalyst was studied with substrates containing acid labile ...
