19F NMR of linear N,N-difluoroaminoalkanes

Whereas most N,N-difluoroaminoalkanes exhibit a single 19F resonance at about +50 ppm, the tri-component mixtures of both N,N-difluoroaminopentanes and N,N-difluoroaminohexanes exhibited a more complex pattern. The individual 1-N,N-difluoroamino-, 2-N,N-difluoroamino- and 3-N,N-difluoroaminopentanes have been synthesized and their separated resonances are reported.
