Abstract

The coordination chemistry of 5-hydroxypyrazoline ligand class 1 modified by 2-thienyl substituents with Ni(OAc)₂ and DMAP as co-ligand to form the nickel complexes 4 [Ni(1-2H)(dmap)_x] was investigated. The complexes were characterized and investigated by various techniques, pointing out different complex geometries, octahedral vs. square planar, depending on the connectivity of the 2-thienyl substituent. In more detail, X-ray crystallography revealed an O,N,O′-coordination in which the ligand is planar and the other coordination sites on the nickel center are occupied by one or three DMAP co-ligands, respectively. Moreover, the complexes have been applied as precatalyst in nickel-catalyzed hydrodecyanation reactions.
