Eosin Y, a well-known economical alternative to metal catalysts in visible-light-driven single-electron transfer-based organic transformations, can behave as an effective direct hydrogen-atom transfer catalyst for C?H activation. Using the alkylation of C?H bonds with electron-deficient alkenes as a model study revealed an extremely broad substrate scope, enabling easy access to a variety of important synthons. This eosin Y-based photocatalytic hydrogen-atom transfer strategy is promising for diverse functionalization of a wide range of native C?H bonds in a green and sustainable manner.

The study of equilibrium between lactonic and amphoteric forms of molecular eosin and fluorescein proves that, in 11 organic solvents, the lactonic ring of fluorescein is more stable than eosin's while in solid state or in aqueous media, the contrary takes place.The influence of solvents is explained by taking account of their solubility parameters δA and δH.
