Diarylphosphine
WebSep 19, 2024 · Abstract The low-cost cobalt (II) catalyst has been used for the first time to achieve P (O)-radical-mediated bisfunctionalization of alkenes with diarylphosphine oxide and peroxides. This simple process is performed under mild conditions to afford a wide variety of phosphonation-peroxidation products in a one-pot manner.
