Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 148043-73-6, name is 4,4,5,5,5-Pentafluoropentan-1-ol. A new synthetic method of this compound is introduced below., Safety of 4,4,5,5,5-Pentafluoropentan-1-ol
4,4,5,5,5-Pentafluoropentan-1-al (or related compounds) has already been described in the literature [see, for example,iii oriv]. Here, 4,4,5,5,5-pentafluoropentan-1-al was prepared by oxidizing 4,4,5,5,5-pentafluoropentan-1-ol under standard conditions (a dichloromethane solution was prepared by reacting with pyridinium dichromate or else by a TEMPO oxidation [see, for example,v]-the dichloromethane solution of the 4,4,5,5,5-pentafluoropentan-1-al was used directly in the Wittig reaction owing to the low boiling point). A Swern oxidation of pentafluoropentanol is problematic [vi].
