in almost quantitative yields. NMR spectra of these compounds show a remarkable dependence upon temperature associated with a low configurational stability around the carbon-nitrogen double bond. An x-ray crystallographic analysis has been performed, showing an unusually short carbon-nitrogen double bond, which might be expected to be longer to explain the mechanism of the facile thermal isomerization
