Carbon-sulfur and carbon-selenium double bond formation through thiolysis and selenolysis of 4-methylsulfanyl-substituted pyridinium and quinolinium halides

4-Methylsulfurylpyridinium and -quinolinium salts 3 and 4 with alkyl groups such as methyl, allyl, benzyl, ethoxycarbonylmethyl, benzoylmethyl on the nitrogen atom were prepared by the Menschutkin-type reaction and some of them caused to react under either the thiolysis or selenolysis reaction conditions. N-Substituted pyridine-4-thiones 5a-c and quinoline-4-thiones 6a-e were formed at different rates in high isolated yield. On the other hand, two N-alkyl-4-selenopyridone 7a,b together with three 4-selenoquinolones 8a,b,c were also produced in high chemical purity and characterized spectroscopically. In addition, 4-sulfanylpyridone 12 and 4-selenopyridone 13 with a N-tert-butyl group were obtained via Zincke' s salt 9. The overall process provides a useful alternative to the otherwise difficult direct N-alkylation of thioxo- and selenoxopyridine systems.
