Synthesis of mono and bis-substituted asymmetrical compounds, (1-(pyridin-2-yl)ethylidene)carbohydrazide and 1-(2-hydroxy-3- methoxybenzylidene)-5-(1-(pyridin-2-yl)ethylidene)carbohydrazide: Structural characterization andantioxidant activity study

We describe the preparation and use of two new imidazolium-bound Rose Bengal derivatives for singlet oxy-gen generation. Photolysis of oxygen-saturated solution of furan rings in the presence of the imidazolium-bound sensitiz-ers provides the corresponding butenolides. The sensitizers could be recovered after the oxidation reaction.
