Transformations of F-Alkyl Iodides and Bromides Induced by Nickel(0) Carbonyl

Adducts of primary F-alkyl iodides with nickel carbonyl are formed readily in donor solvents and pyrolyze at 100-150 °C to give olefinic coupling products in high yield. The mechanism proposed to account for the observed chemistry involves preferential α-elimination of fluorine with formation of a carbenoid species complex coordinated to nickel. Differences in reaction paths among several types of substrate halides are rationalized on the basis of polarization of the Ni-C bond in the adducts. Support for these proposals is provided by state-of-the-art calculations.

Kinetic and Thermodynamic Studies of the Thermal Electrocyclic Interconversions of Perfluorinated Dienes and Cyclobutenes

Detailed kinetic and thermodynamic analyses were carried out for the thermal interconversions of (Z,Z)- and (E,E)-perfluoro-2,4-hexadienes with trans-perfluoro-3,4-dimethylcyclobutene, (E,Z)-perfluoro-2,4-hexadiene with perfluoro-cis-3,4-dimethylcyclobutene, (Z,Z)- and (E,E)-perfluoro-3,5-octadienes with trans-perfluoro-3,4-diethylcyclobutene, and (Z)- and (E)-perfluoro-1,3-pentadiene with perfluoro-3-methylcyclobutene.In each case the (Z,Z)- or (Z)-dienes exhibited substantial kinetic advantage over the (E,E)-or (E)-dienes in their cyclization precesses.
