4-METHOXYBENZYL MERCAPTAN synthesis

9synthesis methods
A mixture of triphenylphosphine (5 mmol) and menthol (5 mmol) in acetone (15 mL) was cooled to -10°C. With stirring at -10°C, a small portion of NBS (5 mmol) was added to this cooled mixture. After complete addition of NBS, the temperature was allowed to

Yield:6258-60-2 89%

Reaction Conditions:

with tetraphosphorus decasulfide in toluene; for 1.5 h;Reflux;

Steps:

General experimental procedure:

General procedure: General experimental procedure: In a three-neck roundbottom flask, to a solution of thiocyanate (10 mmol) in toluene(25 mL), P2S5 (2.22 g, 10 mmol) was added and the resultingsuspension was refluxed till complete consumption of thestarting material (TLC). After the reaction was complete, thereaction mixture was quenched by careful addition of water(10 mL), extracted with ethyl acetate (3 × 10 mL), the organicphase was dried over sodium sulfate and evaporated underreduced pressure to get the crude product which was purified byflash chromatography (hexane-ethyl acetate) to get the purethiol.
