A novel PPh3O catalyzed bromophosphonium salt-mediated dibromination of alpha,beta-unsaturated esters and beta,gamma-unsaturated alpha-ketoesters has been developed. The products were obtained with good to excellent yields and excellent diastereoselectivities. This dibromination reaction is a good complement to the field of dibromination.
