Abstract
The photochemical reactions of indoline-2-thiones in the presence of amines have been examined. Irradiation of indoline-2-thiones 1 in the presence of triethylamine yielded the desulphurization products, indolines 2, along with N,N-diethylthioacetamide 3. The photodesulphurization reactions of indoline-2-thiones 1 can be explained by a sequential electron/proton-transfer mechanism from the amine to the excited indoline-2-thione.Keywords
