The decarboxylation of potassium 2-pyridinyl sulfonyldifluoroacetate and its subsequent reaction with aldehydes was found to be an efficient approach for the Julia-Kocienski reaction under mild conditions to give gem-difluoro olefins in moderate to excellent yields. Owing to its high stability in the pure state and its easy decarboxylation in polar solvents, potassium 2-pyridinyl sulfonyldifluoroacetate is expected to be an efficient gem-difluoro-olefination reagent.
