Photosensitised electron transfer and anodic cyanation reactions of nitrogen heterocycles
Abstract
The u.v. irradiation of nitrogen heterocycles in methanolic sodium cyanide solution, using 1,4-dicyano-benzene or 1-cyanonaphthalene as a sensitiser, gives good yields of the product resulting from ring substitution with the cyanide ion; analogies with anodic cyanation are drawn.
