The temperature dependence of products formed from flash vacuum pyrolysis (FVP) of 2-mercaptonicotinic acid 4 has been studied. FVP of 4 at 550Β°C and ca. 1Γ—10 -2 torr gave pyridothietone 3b and a trimer 5 as the major products. At higher temperature (800Β°C), FVP of 4 gave 2-mercaptopyridine 6 as the
