KETENE GEM-DITHIOLS; A CONVENIENT ONE-STEP PROCEDURE FROM ALIPHATIC ACTIVE METHYLENES: REACTIONS AND SYNTHESIS OF POLYFUNCTIONALLY SUBSTITUTED THIA- AND AZAHETEROAROMATICS

Abstract

It has been reported in the current literature that the isolation of certain ketene gem dithiols has failed due to dimerization. Generation of ketene gem-dithiols via trapping with other reactants led to formation of pyridine VI, pyrroles, pyridothiadiazole and pyrazolone derivatives.

Key Words:

• Ketene gem-dithiols
• sulfur and carbon disulfide with active methylenes
• thia and thiaazoheteroaromatics
