The 2-(chloroseleno)benzoyl chloride is a bifunctional electrophile able to react with C-H acids. The selenenylation and acylation of the active methylene group in the presence of triethylamine, lead to the ring closure. Based on this reaction 2-substituted benzo[b]selenophen-3(2H)-ones and 3-hydroxybenzo[b]selenophenes are produced in moderate to high yields.
