実験手順
33.8 parts of 4-(3,5-di-t-butyl-4-hydroxyphenyl)-1,2-dithiole-3-thione and 40 parts of a 2.5 molar solution of sodium disulphide were dissolved in 40 parts of dimethylformamide and warmed at 100°C for 15 minutes. 500 parts of water were then added, the mixture extracted several times with ether to remove any starting material, and then 60 parts of 3N hydrochloric acid solution were added slowly with stirring. The solid was filtered giving 27 parts of 5-mercapto-4-(3,5-di-t-butyl-4-hydroxyphenyl)-1,2-dithiole-3-thione m.p. 182°C which gave the following elemental analysis:
