Treatment of 1,3-dienes with the pyridinium dichromate (PDC)-t-BuOOH reagent system leads directly to the formation of 4-tert-butyldioxy-2-enones in good yield under mild reaction conditions.

An efficient and unprecedented strategy for the synthesis of 1,4-enediones from saturated ketones has been developed via palladium-catalyzed oxidative dehydrogenation. 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 has been investigated through deuterium-labeling experiments and intermediate experiments.

We have developed an efficient metal-free route for the synthesis of 1,4-enedione derivatives under microwave irradiation by reacting easily available arylmethylketones with DMSO or diphenyl sulfoxide in the presence of TBAI and persulfate. The reaction is very clean and completes within very short time. All the reagents and catalysts are cheap and environmentally benign. In addition, the E-isomer of the products can easily be transformed into the Z-isomer by using eosin Y photocatalyst under the irradiation of white CFL.
