Bimetallic Pt Sn/g Al2O3 catalyzed b alkylation of secondary alcohols with primary alcohols under solvent free conditions
Abstract Heterogeneous bimetallic Pt Sn/g Al2O3 (0.5 wt% Pt, molar ratio Pt:Sn 1:3) was successfully utilized as the catalyst for direct b alkylation of secondary alcohols with primary alcohols under solvent free conditions. b Alkylated secondary alcohols were obtained in moderate to high yields with water formed as the by product through a hydrogen borrowing pathway. The present protocol provides a concise atom economical and environmentally benign method for C C bond formation.
