Abstract
A cross-coupling reaction of arylboronic acids with KSCN salt to yield aryl thiocyanates is catalyzed by copper acetate in the presence of 4-methylpyridine serving both as ligand and base under 0.2 MPa of molecular oxygen. Various arylboronic acids were suitable under the reaction conditions.
