Photochemical α-cleavage from the lowest triplet state (n?*,T1), resulting in the generation of a diradical intermediate, appears to be general for cyclobutanethiones.The diradical intermediate derived from 1,3-dithione is observed to undergo ring expansion to carbene or close to either dithione or dithiolactone.The photochemical behavior reported here for cyclobutanethiones is different from that of the corresponding cyclobutanones. α-Cleavage processes in the case of cyclobutanethiones are not efficient and are often accompanied by side reactions.

Cyclobutanthiones are established to undergo α-cleavage from the lowest n?* triplet state.The diradical intermediates in this reaction are often captured by the ground state thiones and these undergo ring expansion to thiacarbene and/or rearrange to the corresponding dithiolactone.
