Syntheses of gem-difluorocyclopropyl ketones (3a-d) and their reactions with nucleophiles are described.Ring-opening reaction of 3a,c,d having a hydrogen substituent at C1 adjacent to the carbonyl group with a methanolate anion gave carboxylic acid derivatives derived from C1-C2 bond scission (between the carbon atom with an acyl group and the carbon atom with fluorine substituents).On the other hand, reaction of 3a-c with a thiolate anion resulted in the C1-C3 bond cleavage (carbon-carbon bond opposite to the difluoromethylene group).

Syntheses of gem-difluorocyclopropyl ketones (3a-d) and their reactions with nucleophiles are described.Ring opening reactions of 3a, c and d with a methanolate and a thiolate anion took entirely different courses of bond scission of the cyclopropane ring.
