O-Fluoromethyl Carboxylates and O-Fluoromethyl Carbamates
Schlosser, Manfred,Limat, Dominique
, p. 5807 - 5812 (1995)
The fluoride catalyzed reaction between acyl fluorides and monomeric formaldehyde affords fluoromethyl carboxylates in acceptable yields. - Fluoromethyl fluoroformate, readily accessible from the corresponding dichloro compound, condenses with amines to give fluoromethyl carbamates.
