Base-Controlled Three Component Reactions of Amines, Elemental Sulfur, and Styrenes: Synthesis of Thioamides under Metal-Free Conditions

Three component reactions of olefins, amines, and sulfur were studied. Thioamidation of styrenes is base-controlled, and 2-phenylethanethioamides and benzothioamides were obtained selectively in the presence of two different bases. This protocol offers a simple and efficient procedure for the synthesis of thioamides.

1,2,3-Thiadiazoles. I. Synthesis of Sodium (or Potassium) 1,2,3-Thiadiazole-4-thiolates via Thiocarbazonate Esters and N-Acylthiohydrazonate Esters

A general synthesis of 1,2,3-thiadiazole-4-thiolates 1 and their derivatives 2-3 by an extension of the Hurd-Mori 1,2,3-thiadiazole synthesis is described.Treatment of methyl (or ethyl) hydrazinocarboxylates 11 (thiocarbazonate es

Infrared spectra of several thiopiperidides and thiomorpholides

Infrared spectra in the 1700-500 cm-1 region have been studied for several types of thiopiperidides (thiobenzoylpiperidides, thiocinnamoylpiperidides and phenylthioacetpiperidides) and for the corresponding thiomorpholides.Three characteristic thioamide bands were located and assigned.The behaviour of these bands on molecular complexing (with iodine as an electron acceptor) was used to support the assignments.The experimental data were discussed in terms of the theoretical results obtained by an HMO procedure.
