Manganese, rhenium and cyclometalated ruthenium complexes were used as catalysts for the α-alkylation of ketones with alcohols, a reaction creating new C‒C bonds while producing water as sole stochiometric by-product. This reaction was used for the alkylation of a broad scope of ketones including biologically relevant compounds like hormones with various alcohols.
