Reaction of Active Methylene Groups with 1,2-Di(Bromoseleno)Benzene toward Benzo-1,3(2H)-Diselenoles

The 1,2-di(bromoseleno)benzene has been found to be a bifunctional electrophile able to react with C-H acids. The tandem diselenylation of the active methylene group in β-diketones, β-keto- and β-cyanoesters, diethyl malonate, and malonitrile resulted in the ring closure on the carbon atom. Based on...

Abstract The 1,2-di(bromoseleno)benzene has been found to be a bifunctional electrophile able to react with C-H acids. The tandem diselenylation of the active methylene group in β-diketones, β-keto- and β-cyanoesters, diethyl malonate, and malonitrile resulted in the ring closure on the carbon atom. Based on this reaction, 2,2-disubstituted benzo-1,3(2H)-diselenoles, a new group of selenaheterocycles, were obtained in good yields.
