Abstract: Acetyl hypofluorite, H3CC (0) OF, has been prepared by passage of diluted fluorine through solid KOAc. 2HOAc and isolated by trapping at-78" C. It is a slightly yellow liquid (mp ca.-96" C) with a vapor pressure of about 4 torr at-40" C. Vapor-pressure measurements between-64 and-20" C lead to an enthalpy of vaporization of 35.6 f 2.4 kJ/mol and an extrapolated normal boiling point of 53 f 6" C. At-78" C, in 1: l (v/v) CCI4: CDCl3, its I9F ...
