Palladium-catalyzed phosphorus-carbon bond formation: cross-coupling reactions of alkyl phosphinates with aryl, heteroaryl, alkenyl, benzylic, and allylic halides and triflates

The palladium-catalyzed cross-coupling of alkyl phosphinates with various electrophiles is presented. Various H-phosphinate esters can be prepared conveniently in a single step. The reactions of alkenyl and allylic halides are studied for the first time. Some mechanistic aspects of the reaction are also discussed.
