Perfluoroallylic complex

Attempts to prepare perfluoroallyl complexes from metal carbonyl anions and perfluoroallyl chloride have been unsuccessful the perfluoroallyl rearranges and metal-o-propenyl complexes are isolated [84, 85]. However, treatment of perfluorocyclohexa ene iron tricarbonyl with caesium fluoride gives the anionic 21-perfluorocyclohexenyl complex 2.23. 

Parameters for the -perfluoroallylcobalt complex [164], formed by the reaction of perfluoroallyl iodide with Zn[Co(CO)4)2 are given with the structure. (85) The prop-l-enyl complex [165], identified as trans about the double bond by the large value of 7(F-F), was also formed, and an octet at 3 -41-6, with coupling constants similar to those of... 

The temperature dependence of collisional energy transfer in the photoisomerization of cycloheptatriene has been discussed.19 The reactions of singlet methylene with butadiene,20 the excitation of charge-transfer complexes of C2H4-02-Ar mixtures at low temperatures,21 and the photodissociation of the perfluoroallyl cation22 have been reported. The product of the last reaction is the CF3+ ion, and the threshold wavelength for its production is 295 nm.
