Selectfluor-Mediated Simultaneous Cleavage of C-O and C-C Bonds in α,β-Epoxy Ketones under Transition-Metal-Free Conditions: A Route to 1,2-Diketones

Selectfluor-mediated simultaneous cleavage of C-O and C-C bonds in α,β-epoxy ketones has been successfully achieved under transition-metal-free conditions. The reaction gives 1,2-diketone compounds in moderate to good yields involving a ring-opening/benzoyl rearrangement/C-C bond cleavage sequence under oxidative conditions.

Visible-Light-Induced Photocatalytic Oxidative Decarboxylation of Cinnamic Acids to 1,2-Diketones

A concerted metallophotoredox catalysis has been realized for the efficient decarboxylative functionalization of α,β-unsaturated carboxylic acids with aryl iodides in the presence of perylene bisimide dye to afford 1,2-diketones.

A method for synthesizing derivatives benzil

The invention discloses a method for synthesizing a benzil derivative. The method comprises the following steps: adding epoxy chalcone compound shown in the formula I, a Selectfluor oxidizing agent and inorganic base into a mixed solvent of acetonitrile and water, stirring for reaction for 4-8 h at 60-100 DEG C, and treating a reaction liquid obtained after the reaction is finished to prepare the benzil derivative shown in the formula II. The synthesis method has the advantages that the raw materials are cheap and easy to obtain, transition metal catalysis is not needed, the oxygen source is easy to obtain and environment-friendly, the reaction condition is mild, the target substrate can be synthesized efficiently, the universality of the functional group is good, and the operation is simple and convenient.

Copper-mediated aerobic oxidative cleavage of α,β-unsaturated ketones to 1,2-diketones

The copper-mediated aerobic oxidative cleavage of α,β- unsaturated ketones to synthesize 1,2-diketones by using potassium acetate as a catalyst and sodium iodide as a promoter in acetic acid is described. The protocol has the advantages of using inexpensive and non-toxic raw materials, high yield and simple work-up procedure. the Partner Organisations 2014.

An efficient and time saving microwave-assisted selenium dioxide oxidation of 1,2-diarylethanones

Selenium dioxide oxidation of 1,2-diarylethanones to corresponding diones by conventional method takes upto 8 hr. The same oxidation under microwave radiations using dimethylsulfoxide as solvent reduces the reaction time considerably (30 to 90 sec). The method reported is efficient and time saving.
