Abstract
The acceleration of SNAr reaction of aromatic halides has been studied with various amines under high pressure. Compounds having high steric hindrance as 2-morpholino-substituted polychloro-1-nitrobenzenes were obtained. Thes e showed different behaviours of methylene protons of morphlino ring at roo m temperature apparently related to the higher steric hindrance. So these c ompounds were investigated using dynamic H-1 NMR and single crystal X-ray c rystallography.
