PALLADIUM COMPLEXES OF CURCUMIN AND ITS ANALOGUES AND METHODS OF PREPARATION OF THE SAME

摘要

The invention relates to palladium(II) complexes of curcumin and its analogues of general formula (Formula (A)) wherein R1 and R2 are each independently hydrogen, hydroxy, methoxy or ethoxy, as well as the process for preparing the same by reacting the complex compounds [(tmcyda)Pd(OAc)2 ] or [(dmpip)Pd(OAc)2] of general formula ((Formula (B) with curcumin or its analogues of general formula (Formula (B)) wherein R1 and R2 are the same as defined above, in an alcohol having 1 to 4 carbon atoms, or in chlorinated solvents, selected from the group comprising chloroform and dichloromethane, for 12 to 140 hours at the temperature of 15 to 50 °C.
