Tert-Butyl nitrite → Benzene, 1-bromo-2-(methylthio)-4-(trifluoromethyl)-

참여 물질

반응 단계

t-Butyl nitrite (3 ml) was added to a mixture of 3-amino-4-bromobenzotrifluoride (4 g) and dimethyl disulphide (15 ml) in chloroform. The mixture was warmed until reaction started when t-butyl nitrite (11 ml) and a solution of 3-amino-4-bromobenzotrifluoride (16 g) in chloroform were added simultaneously. The resultant mixture was stirred for 24 hours, washed with water, hydrochloric acid (2M), water, dried (MgSO4) and filtered. The filtrate was evaporated to dryness and the residue was distilled to give 4-bromo-3-(methylsulphenyl)benzotrifluoride (16.4 g) as a yellow oil, b.p. 84°-88° C. at 2 mm Hg.
