Versuchsvorschrift

A solution of 5.47 g. (0.026 mole) of O-ethyl S-n-propyl phosphorochloridothioate in 20 ml. of acetonitrile is charged in one portion to a solution of 6.65 g. (0.025 mole) of 4-(benzenesulfonyloxy)thiophenol in 200 ml. of acetonitrile. The solution is stirred and cooled to 4° C. while 2.53 g. (0.025 mole) of triethylamine in 20 ml. of acetonitrile is added dropwise over a 30 minute period. The mixture is held at 5° C. for an additional hour and then concentrated in vacuo. The residue, a mixture of oil and solid, is taken up in 200 ml. of benzene and filtered to remove amine hydrochloride. The filtrate is washed once with 50 ml. of 5% sodium bicarbonate, once with 30 ml. of water, once with 30 ml. of saturated sodium chloride, dried over sodium sulfate, and concentrated in vacuo to give 9.1 g. (84%) of the phosphorodithioate as a pale yellow oil. Anal. calc. (found): C 47.2 (47.3); H 4.8 (5.15).
