The reaction of iodine with silver trduoroacetate2 in ethyl ether and the reaction of cyclopentyl iodide with silver n-heptafluorobutyrate in ethyl ether resulted in the formation of, besides the expected silver iodide, peculiar type compounds which merited special attention. Further studies revealed that trifluoroacetic acid and heptafluorobutyric acid reacted with substantial heat evolution with some ethers and tertiary amines forming sta- ...
