Cu-Catalyzed Generation of Alkyl Radicals from Alkylsilyl Peroxides and Subsequent C(sp<sup>3</sup>)–C(sp<sup>2</sup>) Cross-Coupling with Arylboronic Acids
practical method for the Cu-catalyzed C(sp3)-C(sp2) cross-coupling of alkylsilyl peroxides with arylboronic acids. The reductive cleavage of the O-O bond of alkylsilyl peroxides and the desired cross-couplingreactions to afford alkyl-substituted aromatic rings proceed smoothly at room temperature promoted by simple Cu-based catalysts and do not require activation by visible light. The results of mechanistic
