✦ Synopsis

Fifteen new kinds of mixed ligand complexes Cu(x-P)A [P = 2-(COO)C 6 H 4 CONH-C 6 H 4 ; x = H, 2-Cl, 2-CH 3 , 2-OCH 3 , 4-OCH 2 CH 3 ; A = dehydronium Met, Leu, Phen] were synthesized. The thermal decomposition behavior of each complex is studied by TG. Coats-Redfern, MacCallum-Tammer, and Zsako methods are adopted to estimate the values of the apparent activation energy E a , the activation entropy S = , the reaction order n, and the frequency factor A. The results showed that the reaction order is 2/3 for each of the complex. Studies on the mechanism of the thermal decomposition reactions suggested that these reactions all fit the kinetic equation 1 -(1Ξ±) 1/3 = kt.

## Abstract The acidity of malondialdehyde as well as the stability of its 1 :1‐complexes with Ni^II^ and Cu^II^ have been determined (Table). In comparison with the enolates of aliphatic β‐dike‐tones the anion C~3~H~3~O~2~βˆ’ has not only a strikingly reduced basicity, but is also a grossly inferior
