Application

Ligand used in the Pd-catalyzed coupling of malononitrile with aryl halides. Bulky phosphine ligand used with a Pd(0)-triolefinic macrocycle catalyst for Suzuki coupling of aryl bromides and chlorides.
This ligand is applied with Ni as a key intermediate in the formation of cylcopentane compounds.

Cyclopropyl phenyl ketone underwent oxidative addition to Ni(PCy3) generated from Ni(cod)2 and PCy3 to give a nickeladihydropyran, which is a key intermediate for the Ni(0)-catalyzed homo- or heterocycloaddition to give cyclopentane compounds having two carbonyl substituents at the 1,3-position.

Ni(0)-catalyzed dehydrogenation of benzylic-type imines was performed to yield asymmetrical tetra-substituted imidazoles and 2-imidazolines. This was achieved with a single operational step while maintaining good selectivity and atom economy. The catalytic system shows low to moderate tolerance for fluoro-, trifluoromethyl-
