Organotin derivatives of β-hydroxyesters give rise upon heating to a retrocondensation reaction leading to the ketone and an α-organotin ester. Besides this reversible process, the reaction can follow another route, namely the formation of a β-lactone and of the alkenes coming from its decomposition.
