An efficient disubstituted functionalization of [1.1.1]propellane has been developed. The protocol utilizes sulfonyl hydrazides and N-iodosuccinimide, enabling the introduction of iodine and sulfonyl groups into bicyclo[1.1.1]pentane (BCP) in moderate to excellent yields. It has the advantages of simple operation, mild conditions, and broad substrate scope.
