Photocatalysis, as a method of activation of organic molecules, relies on the electron or energy transfer between photoexcited catalysts and substrates, and allows bond formation and breakage under mild conditions. Though the most used photocatalysts - ruthenium or iridium polypyridyl complexes – have already proved their efficiency in multiple reactions, their high cost, laborious synthesis, and generation of heavy-atom wastes prompted chemists towards the search and development of new photocatalytic systems.<br/>Here we demonstrate, that because of the efficient generation of triplet excited state under UV or visible-light irradiation, <i>meso</i>-antracenyl-BODIPY donor-acceptor dyad can catalyze ATRA reactions between bromomalonate and alkenes. Given the ease of the synthesis, availability of the synthetic precursors and readily tunable photophysical and redox properties, these dyads can become a new inexpensive environmentally friendly alternative to the classical organometallic photocatalysts.
