Abstract

The Suzuki-Miyaura cross-coupling of arenediazonium tetrafluoroborate salts with boronic acids catalyzed by Pd(0)/C in alcoholic solvents is a practical, mild and efficient alternative to classical homogeneous conditions. A chemoselective one-pot double cross-coupling allows the synthesis of unsymmetrical terphenyls.
