Willgerodt-Kindler reaction at room temperature: Synthesis of thioamides from aromatic aldehydes and cyclic secondary amines

A simple method for the synthesis of thioamide derivatives in DMSO at room temperature and at 120 °C has been developed. Total 27 compounds were prepared under both conditions via a one-pot, three component reaction between substituted aromatic aldehydes,

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.
