Palladium-Catalyzed Arylation of Allylic Benzoates Using Hypervalent Siloxane Derivatives
摘要:
Palladium-catalyzed cross-coupling of hypervalent arylsiloxane derivatives proceeded in good to excellent yields with allylic benzoates. Arylation occurred with complete inversion of configuration. The scope and limitations of this reaction, an alternative to the Stille coupling, is summarized.
oxidative allylic C(sp3)–H arylation by radical relay using a broad range of heteroaryl boronicacids with inexpensive and readily available unactivated terminal and internal olefins. This C(sp2)–C(sp3) allyl coupling has the advantage of using cheap, abundant, and nontoxic Cu2O without the need to use prefunctionalized alkenes, thus offering an alternative method to allylic arylation reactions that employ
