We report a transition-metal-free coupling of aldehydes and ketones with geminal bis(boron) building blocks. which provides the coupled, homologated carbonyl compound, upon oxidation. This reaction not only extends an alkyl chain containing a carbonyl group, it also simultaneously introduces anew carbonyl substituent. We demonstrate that enantiopure aldehydes with an enolizable stereogenic center undergo this reaction with complete retention of stereochemistry.
