Amines carbonyl difluoride

Carbonyl difluoride is a particularly versatile fluorinating agent, and an important material for the synthesis of organofluorine compounds [1079], Its reactions with perfluoroalkenes gives perfluoroacyl fluorides in the presence of a fluoride ion source, and its facile reaction with amines or alcohols results in the formation of carbamoyl fluorides or fluoroformates, respectively. The fluorination of carbonyl compounds, such as aldehydes and ketones, with COF can give gem-difluorides by replacement of the carbonyl oxygen atom with two atoms of fluorine e.g.-. 

Ai-Fluoro derivatives have been prepared from the reactions of carbonyl difluoride with secondary amines [850,2193a]. When mixed according to the stoicheiometry indicated in Equation (13.24), dimethylamine reacts at 25 C to form iV-fluorodimethylamine with a yield of 45% [850,2193a]. 

The five-membered heterocyclic ketone (39) has been prepared by the reaction of dimeric 5,5-dimethyl-l,3A, 2,4,5-dithiadiazastannole (40), obtained by the reaction of S4N4 with tris(trimethylstannyl)amine, with an excess of carbonyl difluoride at room temperature. The cyclic, ketone is the first representative of a new class of compounds that have become readily accessible by this method.
