The temperature dependence of products formed from flashvacuumpyrolysis (FVP) of 2-mercaptonicotinic acid 4 has been studied. FVP of 4 at 550°C and ca. 1×10−2 torr gave pyridothietone 3b and a trimer 5 as the major products. At higher temperature (800°C), FVP of 4 gave 2-mercaptopyridine 6 as the major product and 2,2′-dipyridyl disulphide 7 as the minor one.
