Abstract Herein, we present an efficient strategy for the synthesis of spiro(indenyl)cyclohexadienones through radical‐promoted reaction 2‐alkynyl biaryls with sodium sulfinates under electrochemical conditions. The involves sulfonylation and dearomative ipso‐ cyclisation in a domino fashion. This approach features use readily accessible precursors, wide functional group tolerance external oxidant‐free practicality method was also illustrated by scale‐up further diversification product.
