Murata, Yuki published the artcileSynthesis of nitriles via the iodine-mediated dehydrosulfurization of thioamides, Recommanded Product: Pyrazine-2-carbothioamide, the publication is Chemical & Pharmaceutical Bulletin (2020), 68(7), 679-681, database is CAplus and MEDLINE.
A simple general method for the synthesis of nitriles using the inexpensive and easy to handle iodine (I2) is described herein. The reaction of thioamides with I2 in the presence of triethylamine at room temperature under aerobic conditions afforded various nitriles bearing aryl, vinyl, and alkyl groups in good-to-excellent yields. This method was also effective for conversion of thioureas to cyanamides.
