Triethyl amine (2.37) was added and dissolved at room temperature and cooled to -78degreesC. Chloro diethyl phosphite (0.303) was slowly dropped, and temperature of the reaction mixture was made into room temperature. Disodium hydrogen phosphate/sodium dihydrogen phosphate buffer was added and pH was adjusted to 7, and reaction was terminated. Ethyl acetate was extracted and organic layer was washed with saturated salt solution and dried by anhydrous sodium sulfate. Solvent was removed and obtained crude product was purified. Yellow oily substance of 2,3-bis(diethoxy phosphoryl)-1,3-butadiene was obtained. 2,3-bis(diethoxy phosphoryl)-1,3-butadiene (2.02) was dissolved in ethanol, and sodium sulfate nonahydrate (1.63) was added and stirred at room temperature for 3 days. Ethyl acetate was added and 3,4-bis(diethoxy phosphoryl) thiolane was eluted with ethyl acetate. Solvent was removed and crude product was purified to obtain 3,4-bis(diethoxy phosphoryl) thiolane (1.88) with a yield of 84.3%. 3,4-bis(diethoxy phosphoryl) thiolane (3.26) was dissolved in mixed solvent of methanol and water in a ratio of 10:1. Sodium periodate (2.12) was added at room temperature and stirred for 21 hours. The reaction mixture was poured into methylene chloride and diluted. The mixture was stirred for 1 hour and precipitate of sodium iodide was filtered and removed. The obtained organic layer was dried by anhydrous sodium sulfate and 3,4-bis(diethoxy phosphoryl) sulfolane (3.3) was obtained with a yield of 96.9%. 3,4-bis(diethoxy phosphoryl) sulfolane (2.19) was dissolved in methylene chloride, and acetic anhydride (0.714) and methane sulfonic acid (0.14) were added at room temperature and stirred for 6 hours. Potassium carbonate (0.967) was added and reaction was terminated. Solid was filtered and removed and 3,4-bis(diethoxy phosphoryl)-2,3-dihydrothiophene (2.01) was obtained with a yield of 96.4%. Manganese (IV) oxide (9.74) was dissolved in benzene and 3,4-bis(diethoxy phosphoryl)-2,3-dihydrothiophene (2.01) was added at room temperature. The reaction mixture was heated and stirred for 29 hours. The reaction mixture was cooled to room temperature, and solid was filtered and removed. 3,4-bis(diethoxy phosphoryl) thiophene (1.7) was obtained with a yield of 85.4% as brown solid.
