Additives Promote Divergent Reactivity in Photolytic Deoxygenation and Lactonization Reactions of Cobalt Alkoxycarbonyls

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
We report a carbonylation‐homolysis process to access acyl radicals that can undergo decarboxylation or cyclization onto tethered alkenes. In both cases, ligands and additives are shown to influence the outcome to give saturated or unsaturated products, in some cases with isomerization of the initial products.
