Nitrosation () of 1-methyl-2-phenyl-2-imidazoline 8 results in cleavage of only the CN single bond and production of N-(2-methylnitrosaminoethyl)-N-nitrosobenzamide 10. In contrast, 2-phenyl-2-oxazoline 9 nitrosates very rapidly to give products (13–16) derived from a diazonium ion arsing from the exclusive cleavage of the CN.
