โœฆ Synopsis

A method is described for the efficient preparation of a&unsaturated phosphonates and phosphinates from alkenyl triflates via palladium(O)-catalyzed coupling with dialkylphosphites or hypophosphorous acid.

A novel method for the synthesis of stereodefined cyclopropyl-substituted alkenes, based on the Suzuki-type cross-coupling reaction between cyclopropylboronic acids and various alkenyl triflates, is described. It was found that the environment of the alkenyl triflate plays an important role in the r
