Ruthenium sulfophthalocyanine catalyst for the oxidation of chlorinated olefins with hydrogen peroxide

In aqueous solution and at room temperature, various alpha-chloro-alkenes a n effectively dechlorinated by hydrogen peroxide oxidation using a water-so luble ruthenium(II)-tetrasulfophthalocyanine catalyst, RuPcS. The molecular structure of RuPcS has been elucidated by ESI-mass spectroscopy. In the re action conditions, and specifically in acidic media, the complex rapidly gi ves rise to a novel species, most likely catalytically active, whose nature is investigated.
