Doyle-Kirmse rearrangementreactions have received continuous attention as an important method for constructing complex chemical structures. Herein, we disclosed an efficient rhodium-catalyzed Doyle-Kirmse rearrangementreaction, which can simultaneously construct CC bonds and CX (X = SSe) bonds using sulfoxonium ylides as starting materials to obtain sulfur- or selenium-containing compounds. This

The rearrangement of selenium ylides is even today almost unexplored, although it would provide access to important organoselenium compounds with broad downstream applications. In this report, the first systematic study of sigmatropic rearrangement reactions of selenium ylides using a simple rhodium catalyst with catalyst loadings as low as 0.01 mol % is described. Selenium oxide pyrolysis of the rearrangement
