Ligan-ligan asetilpirol fencon azin (8), asetiltiofen fencon azin (11), asetilpirol kamfor azin (10), dan asetiltiofen kamfor azin (12) telah disediakan melalui tindak balas kondensasi bersama dengan fencon hidrazon (5) ataupun kamfor hidrazon (6). Data eksperimen menunjukkan bahawa ligan-ligan (8) dan (10) adalah ligan bersifat penderma bidentat N, N manakala, ligan-ligan (11) dan (12) adalah ligan bersifat penderma bidentat N, S. Semua kompleks yang didapati (13), (14), (15) dan (16) membentuk gelang bercincin enam bersama paladium(II).

Ligands of acetylpyrrole fenchone azine (8), acetythiophene fenchone azine (11), acetylpyrrole camphor azine (10) and acetythiophene camphor azine (12) have been synthesized by the condensation reaction of fenchone hydrazone (5) or camphor hydrazone (6). The experimental data showed that (8) and (10) are bidentate donors N, N ligands. Ligands (11) and (12) are bidentate N, S donors. All complexes (13), (14), (15) and (16) formed a six-membered chelate ring with palladium(II).
