Abstract
Solar photocatalysis is a field of chemistry which is increasing in popularity for use in chemical production. This field has so far been dominated by transition metal complexes, and whilst these can give a variety of products in good yields their sustainability remains an issue. Ruthenium and iridium complexes are problematic due to their scarcity, high price and toxicity. As alternatives to using these complexes organic molecules can be used. These include flavins and Eosin Y, the former being natural molecules whilst the latter is a synthetic dye. These molecules have shown promise in producing a radical on a benzylic carbon.The photocatalytic ability of Eosin Y was investigated in the dehydrogenative coupling of amines as seen in scheme 1.
This oxidative coupling gave very good yields showing good reactivity even with secondary amines, in contrast to previous studies that have been done on the dehydrogenative coupling reactions. Additionally, mechanistic studies have been carried out on the photocatalytic reaction of benzylamine, supporting the proposed mechanism involving a one electron oxidation of benzylamine, which was also in agreement with literature.
