A highly efficient [3 + 2] cycloaddition of cyclopropenone derivatives and elemental chalcogens provides 1,2-dichalcogen heterocycles under mild reaction conditions. Different from other cyclopropenone derivatives, cyclopropenselenones undergo unprecedented rearrangement with elemental sulfur. This protocol offers excellent atom economy, gram-scale ability, and good regioselectivity.
