Abstract EN
The 1H and 13C NMR spectra of 3, 4-dibenzoyl-5-(benzyl amino)-7, 7-dimethylcycloocta-2, 4- diene-1-one and dimethyl 3-(benzyl amino)-5, 5-dimethyl-7-oxocycloocta-2, 8-diene-1, 2-dicarboxylate, at room temperature, are consistent with slow ring inversion.
The energetic barriers for ring inversion in these compounds were determined by dynamic 1H NMR spectroscopy to be 95 ± 2 and 88 ± 2 kJ mol-1, respectively.
The crystal structure of 3, 4-dibenzoyl-5-(benzyl amino)-7, 7- dimethylcycloocta-2, 4-diene-1-one (C31H29NO3) belongs to P21 (1) / n space group with cell dimensions of a = 16.230(3) Å, b = 9.4025(16) Å, c = 17.089(3) Å, β = 114.675(4).
This (Z, Z) cycloocta-1, 3-diene derivative crystallizes in monoclinic space group with Z = 4, the final R value is 0.0518 for 10816 reflections.
