Photochemical Thiocyanation of Halobenzenes with Thiocyanate Anion [PDF]
Bulletin of the Chemical Society of Japan, 1979 Abstract Halobenzenes having such an electrondonating group as amino, hydroxyl or methoxyl group at their para position were thiocyanated with sodium thiocyanate under irradiation. Also, the ring isomer of o-thiocyanatoaniline, 2-aminobenzothiazole, was obtained by the photoreaction of o-chloroaniline with sodium thiocyanate.
