The thermal stability of perfluorinated iodides depends on their structure and decreases in the order of R_FCF2CF2I>R_FCF2CF(CF3)I>R_FOCF(CF3)I=R_FCF2C(CF3)2I.The major decomposition path consists of the elimination of an unsaturated compound (CF2=CF2, CF2=CF-CF3, O=CF-CF3, CF2=C(CF3)2, respectively) with concomitant formation of R_FI.The highest selectivities were found for tertiary iodides and 2-iodo-3-oxaalkanes, whose decomposition is virtually irreversible.UV-photolysis of the iodo-compounds gave the same products as the thermolysis reactions.
