N-Alkylation N-Alkylation O 0268Copper-Promoted C-N and C-O Bond Cross-Coupling with Phenyl and Pyridylboronates. -Acyclic and cyclic esters, as well as anhydride of phenyl boronic acid are efficiently phenylating agents in the title reaction. Furthermore, the first C-N cross-coupling of a heterocyclic boronate (VIII) with heteroarenes, such as (IV) and (VII) is demonstrated. -(CHAN*, D. M. T.; MONACO, K. L.; LI, R.; BONNE, D.; CLARK, C.
