Abstract
Metal dipyrrinato complexes of 4d and 5d metals have distinctive features such as high absorption coefficients in the visible section and room temperature phosphorescence in the red region. This work demonstrates the light-assisted oxidation of organic compounds employing rhenium(I)dipyrrinato complexes as catalysts. The heavy atom effect in rhenium(I)dipyrrinato complexes leads to the formation of long-lived triplet excited states, and these complexes can generate singlet oxygen in excellent yields (up to 84 %). A method was developed for photocatalytic aerobic oxidation of sulfides and amines using only 0.05 mol % and 0.025 mol % of the rhenium(I)dipyrrinato complexes, respectively. The method is efficient, and within 2 h, a variety of substrates were oxidized to produce sulfoxides and imines in high yields (up to 97 %). Rhenium(I)dipyrrinato complexes work very well both in visible light and sunlight, making them promising candidates for photocatalytic applications.
