摘要

Abstract Challenging most chemists' intuition, highly reactive dialkyl biradicals can be reliably generated in the solid state by taking advantage of the photodecarbonylation of cyclic ketones. However, it has been shown that radical stabilizing groups with resonance- delocalizing abilities at the α-carbons of the precursor are required to facilitate the α- cleavage reaction, and that triplet state reactivity is essential to slow down the combination ...
