Benzyl electrophiles alkynylation

There are six discrete combinations for Pd-catalyzed cross-coupling between homoallyl-, homopropargyl-, or homobenzyhnetals and alkenyl or aryl electrophiles (Scheme 4). In addition to these processes, those involving alkyl, allyl, benzyl, propargyl, alkynyl, and acyl electrophiles are conceivable, and some have indeed been observed. However, these reactions are discussed in other pertinent sections. [Pg.622]

The presence of an alkenyl, phenyl, or alkynyl group one carbon away from a halogen, oxygen, or another electronegative atom, such as sulfur, makes allylic, benzyllic, and propargyllic electrophiles very reactive in oxidative addition... [Pg.224]
