Abstract

Abstract : By photoredox-catalysis, alkylation/aryl cyclization of alkynylphosphine oxides towards benzo[ b ]phospholes has been realized under metal- and oxidant-free conditions at room temperature. Abstract : By photoredox-catalysis, alkylation/aryl C–H cyclization of readily available alkynylphosphine oxides towards benzo[ b ]phospholes has been realized under metal- and oxidant-free conditions at room temperature. This reaction readily incorporates various functionalized alkyl groups into the benzo[ b ]phosphole skeletons, representing a mild and versatile tool for the preparation of valuable phosphole compounds.
