Abstract

The energy barrier to rotation about the C(sp2)C(aryl) single bond in non-planar N,N-dimethyl-, N,N-tetramethylene-, N,N-diisopropyl-2,6-difluorobenzamides and in N,N-dimethyl-2-chloro-6-fluorobenzamide was investigated by 19F{1H} NMR in the presence of an optically active shift reagent. The free energy of activation was calculated from the coalescence temperature of the fluorine signals; the ...
