Catalytic Synthesis of 4-(4-Chlorophenoxy)-2-chloroacetophenone and Microwave Promotion in the Reaction
Abstract:
Ullmann reaction of p-chlorophenol(X) with 2,4-dichloroacetophenone(Ⅺ) was studied as functions of catalysts, solvent, reactants ratio and microwave irradiation. The reaction products were characterized by GC-MS, 1H NMR and IR techniques. It is found that some catalysts have good regio selectivity for Ullmann reaction. With Cu2Cl2 as catalyst, AcNMe 2/Xylene as mixed solvent high yield of target compound was obtained. Microwave irradiation was found to accelerate the reaction.
