We developed a mild and practical protocol for the synthesis of 1,4-enedione from α-haloketones through a sodium sulfinate mediated reaction. This reaction enables the construction of symmetric and unsymmetric 1,4-enedione with complete E selectivity. Sodium 4-toluenesulfinate plays an important role in this reaction.

An efficient and unprecedented strategy for the synthesis of 1,4-enediones from saturated ketones has been developed via palladium-catalyzedoxidativedehydrogenation. The protocol employs molecular oxygen as the sole oxidant and represents an atom- and step-economic process. The approach showed broad substrate scope, good functional group tolerance, and complete E-stereoselectivity. The reaction mechanism
