Ligands coordinate to metals through one or more donor atoms bound to the metal. The Cl − and Br − analogues exhibit SMM behavior with energy barriers of 49.1 K and 70.9 K, respectively under a small dc field. It dissolves in non-polar organic solvents such as benzene and diethyl ether. Room-temperature Ni(0)-catalyzed cross-coupling reactions of deactivated aryl chlorides with arylboronic acids with inexpensive triphenylphosphine (PPh3) as a supporting ligand have been accomplished in good to excellent yields.
