A common compound: 2043-55-2, name is 1,1,1,2,2,3,3,4,4-Nonafluoro-6-iodohexane, belongs to iodides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 2043-55-2
Preparation of [CF3 (CF213CH2CH2LO-3H2] A mixture of 37.4 g of [1-IODO-LH, LH,] 2H, [2H-PERFLUOROHEXANE] and 50.0 g of triethyl phosphite was heated at [150 ¡ãC.] After 16 hr, an additional 50.0 g of triethyl phosphite was added, and heating was continued. After 2 hr, an additional 50.0 g of triethyl phosphite was again added, and heating was continued for another 24 hr. Diethyl ethylphosphonate and other volatiles were removed by distillation through a 12-inch (30 cm) vacuum- jacketed packed column, b. p. [34-38 ¡ãC] at 0.05 torr (7 Pa). Distillation of the concentrate provided 22.3 g of [1-DIETHYLPHOSPHONO-LH, LH,] 2H, 2H-perfluorohexane as a 90: 2: 7 mixture with triethyl phosphate and ethyl 1H, lH, 2H, 2H-perfluorohexyl ethylphosphonate as a clear, colorless liquid, b. p. [47-51 ¡ãC] at 0.05 torr (7 Pa).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2043-55-2, other downstream synthetic routes, hurry up and to see.
