The key to the success of a general catalytic procedure for the cross-coupling of primary amides and alkylboronic acids was the identification of a mild base (NaOSiMe3) and oxidant (di-tert-butyl peroxide) to promote the copper-catalyzed reaction in high yield. This transformation provides a facile, high-yielding method for the monoalkylation of amides.
