Merging [2 2] Cycloaddition with Radical 1,4 ‐Addition: Metal‐Free Access to Functionalized Cyclobuta[a]naphthalen‐4‐ols

AngewchemMerging [2 2] Cycloaddition with Radical 1,4 ‐Addition: Metal‐Free Access to Functionalized Cyclobuta[a]naphthalen‐4‐ols: A metal ‐free [2+2] cycloaddition and 1,4‐addition sequence induced by S‐centered radicals has been achieved by treating benzene‐linked allene‐ynes with aryldiazonium tetrafluoroborates and DABCO‐bis(sulfur...
