چکیده
|
At first, new pendant schiff base pvc-en-3mssb was prepared by modification of pvc at the presence of ethylene diamine and 3- methoxy salicylaldehde (3ms). then, from the reaction of pvc-en-3mssb and cu(oac)2 or vo(acac)2, pvc pendant complexes pvcen- 3mssb-cu (1) and pvc-en-3mssb-vo (2) were prepared. all compounds were characterized by ft-ir, xrd, tga, dta and tem. ft-ir and xrd results confirmed the preparation of all compounds. tga results show that the stability of complex 1 is higher than 2 and pvc-en-3mssb. in addition, the catalytic properties of the complexes in knoevenagel condensation for synthesis of 4- hydroxysalicydenebarbituric acid are investigated and the results show that the vanadium(iv) complex has a better catalytic properties.
