Embodiment 1
[0042] Preparation of 2-carbonyl-3-phenylpropionic acid salicylhydrazone di-n-butyltin complex:
[0043] Add 0.249g (1.0mmol) di-n-butyltin oxide, 0.152g (1.0mmol) salicylic hydrazide, 0.205g (1.1mmol) sodium phenylpyruvate and 15mL solvent anhydrous methanol in a 100mL three-necked flask protected by nitrogen. React at a temperature of 45~65°C for 8 hours, cool, filter, and control the solvent volatilization and crystallization at 20~35°C to obtain a yellow transparent crystal, which is 2-carbonyl-3-phenylpropionic acid salicylhydrazone di n-Butyltin complexes. Yield: 83.3%. Melting point: 164~166°C (dec).
[0044] Elemental analysis (C 24 h 30 N 2 o 4 Sn): Calculated: C 54.47, H 5.71, N 5.29; Found: C 54.50, H 5.70, N 5.26.
