experimental part, p. 1225 - 1228 (2010/12/20)
A convenient one-pot preparation of N-substituted thioamides from acyl halides, amines and H2O/PSCl3/Et3N in good to excellent yield has been reported through a solvent-free, microwave assisted method.

Starting from acetamides 4 and using three different routes - via thioacetamides 5, 3-amino-thioacrylamides 7, or 3-chloropropeniminium salts 6 - a series of new N,N-dialkyl derivatives of 2-amino-5-thiophenecarboxylates 10 has been prepared and analytically and spectroscopically characterized.

Iradiation of 1,2,3-thiadiazole together with diethylamine in liquid solution at room temperature or at 150 K gives rise to N,N-diethylthioacetamide in high yield which implies trapping of thioketene during photolysis.Experiments with -1,2,3-thiadiazole at room temperature demonstrate lack of carbon randomization the thioacetyl group of the trapping product.The excludes thiirene as a potential precursor for thioketene at this temperature.The products isolated after irradiation of -1,2,3-thiadiazole together with diethylamine in an EPA glass at 77 K show up to 37percent carbon randomization in the thioketene.This strongly supports a reaction mechanism where thiirene is formed by photolysis of thioketene in solid solution and rapidly reverts to thioketene, resulting in the observed carbon randomization.This process does not occur in liquid solution owing to the extremely small steady-state concentration of thioketene during photolysis.The photolytic reaction of 1,2,3-thiadiazole in EPA at 77 K was monitored by UV spectroscopy and the spectrum of thioketene is reported.
Photochemical Desulphurization of Indoline-2-thiones

, 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
