Small-Ring Compounds. XXXV. Studies of Rearrangements in the Nitrous Acid Deaminations of Methyl-substituted Cyclobutyl-, Cyclopropylcarbinyl- and Allylcarbinylamines

Abstract

The compositions of the alcohol mixtures formed in nitrous acid deaminations of cyclopropylmethylcarbinylamine, (2-methylcyclopropyl)-carbinylamine, 2-methylcyclobutylamine, 3-methylcyclobutylamine, crotylcarbinylamine and allylmethylcarbinylamine have been determined. These results and the behavior of the corresponding alcohols under isomerization conditions in strongly acidic media may be explained by assuming formation of three non-equivalent, unsymmetrical, non-classical cationic intermediates analogous to those previously proposed for the carbonium ion reactions of other small ring derivatives
