- W2977421921 abstract "Four novel Z-N type catalysts,2,2-diisobutyl-1,3-propylene glycol dichloro-benzoates(4a~4d) were synthesized from diethyl malonate and chloro-benzoyl chloride by the reaction of alkylation,ester reduction and acylation in total yields of 73%～80%.The structures were characterized by 1H NMR.Catalytic activities of 4a~4d were investigated by polymerization of propylene.The results showed that 4a~4d exhibited good catalytic activities.The catalytic activities were increased by introducing chloro group on benzene ring and were highest when chloro located on the meta position of carboxylic group." @default.
