Methanethiol → HCID 73867527, compound

Participants

Reaction Steps

4.1 g of 1,3-bis(benzylideneamino)-2-(methylthio)imidazolium tetrafluoroborate in 25 ml of absolute acetonitrile are treated under an argon atmosphere with 1.45 g of absolute morpholine, whereby the evolution of methylmercaptan sets in immediately and solution occurs. The solution is left to stir overnight at room temperature until the cleavage of methylmercaptan is complete. The resulting colorless precipitate is removed by filtration. The filtrate is treated with 30 ml of diethyl ether and again filtered. The two filter residues are combined and reprecipitated from acetonitrile/ether. There is obtained 1,3-bis(benzylideneamino)-2-morpholinoimidazolium tetrafluoroborate in the form of colorless crystals of m.p. 244°-247° (dec.).
