Photo-Arylation. VII. Photoreaction of 2-Halopyridine with Indole

Seki, Koh-Ichi,Ohkura, Kazuke,Terashima, Masanao,Kanaoka, Yuichi

, p. 940 - 944 (2007/10/02)

Photolysis of 2-halopyridine with indole afforded the (2-pyridyl)indoles as a regioisomeric mixture.On the basis of the isomer distributions, an electron transfer mechanism is suggested for the present reaction.The regioselectivity was found to be fairly dependent on the solvent polarity. Keywords---(2-pyridyl)indole; photoarylation; photolysis; 2-halopyridine; indole; electron transfer; solvent effect; isomer distribution
