, p. 141 - 143 (2007/10/02)
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.T

Reduction of indolin-2-ones with lithium aluminium hydride (LAH) or diisobutylaluminium hydride (DIBAL) and desulfurization of indoline-2-thiones with Raney-Ni were investigated.Treatment of indolin-2-ones 1 with LAH or DIBAL yielded indoles 4 and/or indolines 3 in moderate-to-high yields depending on the substituents at N and C(3) of 1.Indoline-2-thiones 2 were desulfurized with Raney-Ni tigive indoles 4 and/or indolines 3.

The phenylation of enols and of enolate anions of ketones, β-diketones and keto esters has been studied using a range of Bi reagents.Under basic conditions C-phenylation is observed and, even hindered, perphenylated compounds are easily synthesized.Under neutral and acidic conditions ordinary ketones do not react and enolic systems give O-phenylation.A number of other anions have been phenylated under basic conditions, including the key compound indole wich mainly gave 3-C-phenylation.All these reactions can be supposed to have one of two alternative mechanisms, which parallel the two mechanisms proposed for the phenylation of phenols.
