Photo-induced 1,2-alkylarylation/cyclization of alkenes, alkyl halides and N-alkylindoles via an EDA-complex

Herein, we developed a photo-induced 1,2-alkylarylation and 1,2-alkylarylation cyclization of alkenes, alkyl halides and N -alkylindoles to synthesize indoles derivatives and polysubstituted tetrahydrofuran under mild conditions without the use of external redox reagents and photosensitizers.
