Regioselective radical cyclization by electrochemical reduction using an arene mediator. environmentally benign method
Electrochemical reduction of 2-(but-3-enyl)-1-haloarenes in the presence of phenanthrene as a mediator generated the corresponding aryl radicals and gave cyclized products in good yields. Higher regio- and stereoselectivities than those of usual radical cyclization using AIBN-TBTH were achieved.
