Catalytic Oxidation of 2-Mercaptoethanol by Cobalt(II)phthalocyanines Bearing Chalcone with Furan and Thiophene

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