New couple: The Cu-promoted trifluoromethylation of primary and secondary alkylboronic acids with TMSCF3 extends the scope of transition-metal-catalyzed trifluoromethylation reactions to sp3-hybridized carbon centers. It also represents one of the first examples for Cu-catalyzed C[BOND]C cross-coupling reactions of alkylboronic acid derivatives.
