The long-lived triplet excited states of transition metal photocatalysts can activate organic substrates via either energy- or electron-transfer pathways, and the rates of these processes can be influenced by rational tuning of the reaction conditions. The characteristic reactive intermediates generated, however, are distinct and can exhibit very different reactivity patterns. This mechanistic diversity
Ethyl azol-2-ylglyoxylates react smoothly with acetone in the presence of catalytic amounts of proline and trifluoroacetic acid to give the corresponding azolyl aldols in 93-98% yield. The products are easily transformed into azolyl pyridazinones in 85-98% yield by cyclization with hydrazine hydrate.
