Abstract

The diimine 2-diacetylpyridine-(1R)-(-)-fenchone azine {fench=NN=CMe}C5H5N (4) was prepared by heating 2-diacetylpyridine with fenchone hydrazone (3) in boiling ethanol in the presence of acetic acid as the catalyst. Treatment of [Mo(CO)4(nbd)], [Cr(CO)4(nbd)] or [W(CO)4(nbd)] (nbd = norbornadiene) with 2-diacetylpyridine-(1R)-(-)-fenchone azine {fench=NN=CMe}C5H5N (4) gave the five-membered chelated N,N bonded carbonylcomplex of (5), (6) or (7), respectively. Treatment of [PdCl2(NCPh)2] with the azine ligand (4) gave the palladium-complex (8). Treatment of (8) with LiBr or NaI gave the metathesis product of (9) or (10), respectively. Treatment of [{(η3-2-MeC3H4)PdCl2}2] with the azine ligand (4) gave the chloride salt which was then isolated as the corresponding PF6 salt (11).
