phosphine-free pincer ruthenium(III) catalyzed β-alkylation of secondaryalcohols with primary alcohols to α-alkylated ketones and two different secondaryalcohols to β-branched ketones are reported. Notably, this transformation is environmentally benign and atom efficient with H2O and H2 gas as the only byproducts. The protocol is extended to gram-scale reaction and for functionalization of complex vitamin E
