Synthesis of 4-(2-Hydroxy-5-methylphenyl)-1,3-Dithiol-2-ylidene Derivatives

Abstract

The reaction of 4-(2-hydroxy-5-methylphenyl)-1,3-dithiolium perchlorates with various methylene active compounds has provided the corresponding 1,3-dithiol-2-ylidene derivatives. The reactions have been performed under basic conditions using DBU. The newly obtained derivatives were characterized by NMR, MS spectrometry and IR spectroscopy.
