Abstract: Ni(I)-mediated single-electron oxidative activation of alkyl halides has been extensively proposed as a key step in Ni-catalyzed cross-coupling reactions to generate radical intermediates. There are four mechanisms through which this step could take place: oxidative… read more here.

Abstract: We hereby report a visible light mediated alkyl sulfonylative cascade cyclization of alkynyl and dialkynyl cyclohexadienones via SO2 insertion. The protocol utilizes alkyl Hantzsch esters as the alkyl source and DABSO as the SO2 source… read more here.
