Abstract : 3, 4-Dihydropyran was found to form N-(2-tetrahydropyranyl) derivatives with a variety of secondary aromatic amines. The reaction is catalyzed by concentrated sulfuric acid. The structures of these compounds were established by infrared, ultraviolet, and nuclear magnetic resonance spectroscopy. The derivatives are stable as solids and in basic solution, but are decomposed in the presence of alcohols by traces of acid to regenerate the amines. (Author)
