Abstract:X-ray structure of trans-chloro(1-naphthyl)bis(triphenylphosphine)nickel(II) (4) was determined. The complex crystallizes in the triclinic system, space group P 1 with a = 12.0623(3), b = 13.8844(4), c = 14.5261(4) angstrom, = 104.787(2), = 104.861(2), = 107.602(2)degrees, and Z = 2. Dehalogenation of aryl chlorides was successfully performed in isopropyl alcohol (IPA) by using 4 as a precatalyst in the absence of reducing agent. The dehalogenation proceeded smoothly at ambient temperature to provide desired arenes in almost quantitative yields.
