Nickel-catalyzed C-O activation of phenol derivatives with potassium heteroaryltrifluoroborates

Molander, Gary A.,Beaumard, Floriane

, p. 4022 - 4025 (2010)

A general method based on nickel-catalyzed C-O activation of various phenol derivatives with potassium (hetero)aryltrifluoroborates has been developed. A large number of heterobiaryls can be easily obtained with yields up to 99% using methanesulfonate cross-coupling partners.
