Abstract : Perpustakaan Tuanku Bainun

The benzaldehyde_(1R)_(-)_fenchone azine (1) and derivatives (3), (4), (5), (6) and (7) were prepared by heating the desired benzaldehyde derivatives and fenchone hydrazone in boiling ethanol solution in the presence of acetic acid as catalyst for 3 h. Treatment of the ligands (L) with Na2PdCl4H2O or [PdCl2(NCPh)2] in the ratio of 1 : 1 or 2 : 1 gave the complexes of the type PdL2Cl2 (2), (8), (9), (10), (11) and (12) of which the palladium was bonded to the nitrogen near to fenchone residue. Keywords: Fenchone azine, chiral terpene, palladium complexes
