Experimental determination of the conformational free energies (A values) of fluorinated substituents in cyclohexane by dynamic 19F NMR spectroscopy. Part 2. Extension to fluoromethyl, difluoromethyl, pentafluoroethyl, trifluoromethylthio and trifluoromethoxy groups

The synthesis of monosubstituted and 1,4-substituted cyclohexanes bearing one of the title groups is described. The conformational analysis of these compounds was studied by 19F NMR spectroscopy at various temperatures. Chemical shifts for each conformer above the coalescence temperature were obtained by binomial regression from low temperature values, allowing the high precision determination of the equilibrium constants, and the corresponding thermodynamic parameters (ΔG°, ΔH°, ΔS°) of the fluorinated substituents. For A values (-ΔG°298K), the following averaged data were obtained: 1.59 (CFH2), 1.85 (CF2H), 2.67 (C2F5), 0.79 (OCF3) and 1.18 (SCF3) [in kcal mol-1]. the Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2006.

Solvolysis of chiral cyclohexylidenemethyl triflate. Evidence against a primary vinyl cation intermediate

Solvolysis of (R)-4-methylcyclohexylidenemethyl triflate (6) was examined at 140°C in various aqueous methanol and some other alcoholic solvents. The main product was (R)-4-methylcycloheptanone that maintains the stereochemical purity of 6, with accompanying 4-methylcyclohexanecarbaldehyde. In the presence of bromide ion, the bromide substitution product was also obtained, mostly with inversion of configuration. It is concluded that the solvolysis does not involve the formation of the primary vinyl cation but proceeds via σ-bond participation to form the rearranged cycloheptenyl cation as an intermediate.
