Abstract :
Benzyl thiocyanates with an electron-withdrawing group (1a, 1b) and 9-fluorenyl thiocyanate (1e) rearrange to the corresponding isothiocyanate (2) under 9,10-diphenylanthracene (DPA) sensitization. The rearrangement would proceed via carbon–sulfur bond cleavage in an anion radical of 1 produced by photoinduced electron transfer, followed by back electron transfer to DPA·+ and recombination of the resulting radical or ion pair.
