With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.355-80-6, name is 2,2,3,3,4,4,5,5-Octafluoro-1-pentanol, molecular formula is C5H4F8O, molecular weight is 232.0719, as common compound, the synthetic route is as follows.355-80-6
EXAMPLE 4 2,2,3,3,4,4,5,5-Octafluoro-n-pentanol (11.6 g, 0.05 mol) and sodium metal (1.4 g, 0.05 mol) were added to 100 ml of dry ether and stirred at room temperature overnight. The solution obtained was added into a solution of 1,2-dichlorohexafluorocyclopentene (12.3 g, 0.05 mol) in 100 ml of dry ether. The reaction mixture was poured into 150 ml of ice water and an organic layer was separated. The aqueous layer was then extracted with 3 portions of 100 ml ether. Next, the extracts were combined with the separated organic layer and dried over sodium sulfate overnight. The desired 2-chlorohexafluorocyclopentyl 2,2,3,3,4,4,5,5-octafluoro-n-pentyl ether (38-42 C./0.3 mmHg) was obtained in 50% yield based on 1,2-dichlorohexafluorocyclopentene used by vacuum distillation.
Statistics shows that 355-80-6 is playing an increasingly important role. we look forward to future research findings about 2,2,3,3,4,4,5,5-Octafluoro-1-pentanol.
