Abstract
Two amino-benzotriazole phenol ligands, 2-(2H-benzotriazol-2-yl)-6- ((diethylamino)methyl)-4-alkyl-phenol (alkyl = CH3, C1DEABTP-H, and alkyl = C8H17, C8DEABTP-H) were prepared through the Mannich condensation of 4-alkyl-2-(2H-benzotriazol-2-yl)phenol with the mixtures of excess paraformaldehyde and diethylamine under reflux conditions. Zinc complexes supported by amino-benzotriazole phenoxide ligands (C1DEABTP - and C8DEABTP-) were synthesized and fully characterized. The reaction of ZnEt2 with DEABTP-H (1 equiv.) produces the tetra-coordinated dimeric zinc complexes [(μ- C1DEABTP)ZnEt]2 (1) and [(μ-C8DEABTP)ZnEt] 2 (2). Experimental results indicate that complex 1 catalyzes the ring-opening polymerization of ε-caprolactone and β-butyrolactone with good catalytic activities in a controlled character.
