Abstract

Abstract 1-Acetyl-[1a; 3, 5-CF 3, 1-C (= O) CH 3] and 1-benzoyl-5-hydroxypyrazolines [1b; 3, 5-CF 3, 1-C (= O) C 6 H 5] have been synthesized and treated with Ni (OAc) 2· 4H 2 O in the presence of an excess of base [NH 3 or 4-(dimethylamino) pyridine (DMAP)] to form the nickel complexes 4a–c. These complexes have been characterized by various techniques, which indicate a tridentate coordination mode of the ligands. X-ray crystallography ...
