实验步骤: Triphenylmethyl mercaptan (0.050 g, 0.18 mmol) was dissolved in anhydrous methylene chloride and cooled to 0° C. Tert-butyl nitrite (0.186 g, 1.80 mmol) was added and the resulting mixture was stirred at 0° C. for 30 min. The reaction mixture was allowed to warm to room temperature and stirred at room temperature for 1 hour. The solvent and excess of tert-butyl nitrite were evaporated to give the title compound as a green solid (0.054 g, 98%). 1H NMR (CDCl3) δ: 7.13-7.18 (m, 4 H), 7.25-7.39 (m, 11 UH). to warm to room temperature stirred at room temperature for 1 hour The solvent and excess of tert-butyl nitrite were evaporated

实验步骤: Triphenylmethylmercaptan (362.94 g, 1.31 mol, 100 mol %) dissolved in anhydrous THF (2 L) was cooled in an ice bath under argon. Sodium hydride (60% in oil; 54.39 g, 1.35 mol, 104 mol %) was added in portions over 20 min. 2-bromo-2-methylpropanal (206.06 g, 1.36 mol, 104 mol %; see Stevens & Gillis, 1957, J. Amer. Chem. Soc. 79: 3448-51) was then added slowly over 20 min. The reaction mixture was allowed to warm to room temperature and stirred for 12 hours. The reaction was quenched with water (1 L) and extracted with diethyl ether (3×1 L). The ether extracts were combined, washed with saturated NaCl solution (500 mL), dried over Na2SO4 and filtered. The solvent was removed under reduced pressure to afford a thick orange oil. The crude oil was dissolved in toluene (200 mL) and diluted to 2 L with hot hexanes. The mixture was filtered through a sintered glass funnel and cooled at −5° C. for 12 hours. The white crystalline solid which formed was removed by filtration to afford 266.36 g (59% yield) of the title compound. The melting point of the resulting compound was determined to be 83-85° C. Nuclear magnetic resonance characterization experiments yielded the following molecular signature: was cooled in an ice bath under argon The reaction was quenched with water (1 L) extracted with diethyl ether (3×1 L) washed with saturated NaCl solution (500 mL) dried over Na2SO4 filtered The solvent was removed under reduced pressure to afford a thick orange oil The mixture was filtered through a sintered glass funnel cooled at −5° C. for 12 hours The white crystalline solid which formed was removed by filtration

实验步骤: To a suspension of 100.4 g. (0.40 mole) of triphenylmethylmercaptan in 500 ml. of dry dimethylformamide was added 40.4 g. (0.40 mole) of dry triethylamine. The reaction mixture was cooled in ice and stirred as portions of 54.2 g. (0.40 mole) of the product of Step A above were added over 10 minutes. The reaction mixture was stirred an additional hour with ice cooling and then overnight at room temperature. Water was then added carefully to the reaction mixture until just before the cloud point, when the mixture was seeded and crystallization began. Yield of product was 98.5 g. with an m.p. of 147°-149° C. To a suspension of 100.4 g The reaction mixture was cooled in ice The reaction mixture was stirred an additional hour with ice cooling overnight at room temperature crystallization

实验步骤: A mixture of 0.009 mole of triphenylmethyl mercaptan and 0.009 mole of triethylamine in 10 ml. of dimethylformamide is cooled to 0°-5° C. in an ice bath and 0.009 mole of N-acetyl-2-chloroacetamide added. The reaction mixture is stirred at ambient temperature for three hours and then poured into 100 ml. of benzene and 100 ml. of water. The organic layer is separated, washed well with water, dried over sodium sulfate and concentrated to dryness. The residue is crystallized under petroleum ether to give 2.2 g. of Nacetyl-2-(triphenylmethylthio) acetamide. poured into 100 ml The organic layer is separated washed well with water dried over sodium sulfate concentrated to dryness The residue is crystallized under petroleum ether to give 2.2 g
