Preparation of E-1,2,3,3,3,-Pentafluoropropene, Z-1,2,3,3,3-Pentafluoropropene and E-1-Idopentafluoropropene.

摘要

A two-liter three-necked round bottomed flask was equipped with a magnetic stirbar, dry ice condenser, rubber septum and glass stopper. The apparatus was dried with a Bunsen burner under a stream of nitrogen. The flask was charged with 110 ml dry ether and cooled to -78 C Dry Ice, isopropyl alcohol. Hexafluoropropene (32 ml, 320 mmol), previously measured by condensation into a graduated tube was added via the dry ice/isopropyl alcohol filled condenser. Reprints.
