Dibenzothiophene-5-oxide (DBTO) cleanly produces dibenzothiophene (DBT) on direct photolysis, but with very low quantum yield. A proposed mechanism involves scission of the S−O bond which is coupled to an intersystem crossing step, thus producing the sulfide and O(3P) via a unimolecular pathway. To test this hypothesis, heavy atom substituted DBTOs were prepared and photolyzed. Iodo-, bromo-, and chloro-substituted

An operationally simple and practical method for the reduction of sulfoxides into sulfides using tetrahydroxydiboron [B2(OH)4] as a deoxygenative agent in the absence of catalyst and additive is described. A wide range of diaryl-, dialkyl- and aryl/alkyl-sulfoxides was successfully converted into corresponding sulfides in 92–99% yields. The applicability and practicability were demonstrated by 36 examples
