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.

A series of 8-heteroaryl substituted quinolines were prepared, either by direct C–H arylation of five-membered heteroarenes, or Pd-catalyzedcoupling of organoboron reagents with bromoquinolines. The use of (benzo)thiophenyl or (benzo)furanyl boron coupling partners allowed further C–H functionalization on the five-membered heteroaryl ring with aryl bromides in one flask to access a variety of polyconjugated
