Cobalt(II) phthalocyanines carrying on the four of the peripheral positionsfuran and thiophene as chalcones were sythesized. THF is used to investigate the catalyticoxidation of 2-mercaptoethanol. Thesynthesized phthalocyanines show catalytic activity on the oxidation of2-mercaptoethanol. Cobalt (II) phthalocyanine derived by chalcone with furanhas given catalytic specifications such as turnover number TON as 16.6, initialreaction rate as 0.293 μmol/secand the oxygen consumption as 10.06 μmol/min.The other cobalt (II) phthalocyanine derived by chalcone with thiophene hasgiven catalytic specifications such as turnover number TON as 15.9, initialreaction rate as 0.213 μmol/sec andthe oxygen consumption as 9.88 μmol/min. So chalcone derived phthalocyanines can be used as catalyst is oxidationof mercaptan by air.
