Synthesis of N-unsubstituted cycloalkylimines containing a 4 to 8-membered ring†
Abstract
Primary cycloalkylimines with a 4 to 8-membered ring were synthesized by dehydrocyanation of the corresponding α-aminonitriles on solid potassium hydroxide via a vacuum gas–solid reaction. Imine–enamine tautomerism has been demonstrated at room temperature for the most kinetically stable derivatives.
