Solid-state NMR study of the kinetics of a ring chain tautomerism in a tetrahydro-1,3-oxazine derivative
Condensation of cis-2-aminomethylcyclohexanol with p-nitrobenzaldehyde under mild conditions initially gives the imine as the kinetically controlled product. The imine undergoes a solid-state rearrangement to the bicyclic tetrahydro-1,3-oxazine. The kinetics of the rearrangement were followed by sol...

| 520 | 3 | |a Condensation of cis-2-aminomethylcyclohexanol with p-nitrobenzaldehyde under mild conditions initially gives the imine as the kinetically controlled product. The imine undergoes a solid-state rearrangement to the bicyclic tetrahydro-1,3-oxazine. The kinetics of the rearrangement were followed by solid-state CP/MAS C-13 NMR spectroscopy over the temperature range 283-297 K and the reaction was shown to have an activation energy of 85.0 +/- 14.7 kJ mol(-1). The probable reaction mechanism is discussed. | |
