✦ Synopsis


Structural assignments for the various synthetic intermediates were confirmed by infrared, proton magnetic resonance and mass spectroscopy on chromatographically homogeneous samples.

This cycloaddition probably involves the intermediacy of a triazoline rather than a nitrene.

See A.L. Logothetis, J. Am. Chem. Sot. _ 87 (4), 749 (1965) for a thorough study of the decomposition of olefinic asides.
