Abstract

Photoreaction of 2-fluoropyridine with indoles gave 1-(2-pyridyl) indoles regioselectively. The yields of the coupling products were improved significantly by using the indole anion derivatives. A reaction mechanism involving charge-transfer excitation is proposed for the latter, while the former reaction was concluded to be caused by local excitations.
