HCID 8028TetrahydrofuranSolvent

Procedure

To a slurry of 16.5 grams (g) of ethylthionophosphine sulfide in tetrahydrofuran, under nitrogen at room temperature, was added 13.8 g (0.133 mole) 1,1-dimethyl-1-propanethiol (tertiary amyl mercaptan). To this mixture was added 18.5 milliliters (ml) (0.133) triethylamine, dropwise. The mixture was stirred one hour at room temperature, then refluxed for 1/2 hour and stripped of solvent. There was obtained 30.1 g (87% of theoretical yield) of the triethylamine salt of S-(1,1-dimethylpropyl)ethylphosphonotrithioic acid).
