Participants

Reaction Steps

To 150 ml of formic acid was added 18.1 g of 4-methyl-1-phenylthiosemicarbazide obtained in the above process and the mixture was heat-refluxed for 20 hours. After cooling the reaction mixture and crystals thus formed were collected by filtration and recrystallized from methanol to provide mesoionic 4-methyl-1-phenyl1,2,4-triazolium-3-thiolate as light yellow crystals.
