反应实例

O-p-t-Butylphenyl dimethylthiocarbamate(8). To dimethylthiocarbamoyl chloride 7 (21 g, 0.17 mol) in DMF (140 mL) at 14 C was added all at once dry sodium p-t-butylphenolate 6 (17.6 g, 0.1 mol) (exothermic, temp 26 C). The mixture was stirred for 1.5 h at 30–34 C, added to water (300 mL) and extracted with PhH/Skellysolve B (4:1). Workup, evaporation and recrystallization from MeOH (100 mL) afforded 21.4 g of 8 (95%), mp 97–99 C.

Pyrolysis. Heating 8 neat at 270 C until by TLC the starting material is absent, afforded 9 in a 95%yield.

p-t-Butylphenylthiol (10). A solution of 9 in MeOH was heated under N2 with excess NaOH to give 10 (85%), bp 102–105 C/7–8 mm.
