WebHydrogen bonding in phenol, aniline, and thiophenol has been investigated by n.m.r. spectroscopy and cryoscopy. While phenol shows evidence for the presence of monomer–dimmer–polymer equilibrium, thiophenol only indicates low monomer–dimer equilibrium. The extent of association in these three systems decreases in the order … WebThe amination of phenol to aniline is a sustainable method to replace the traditional synthesis of primary aniline by nitrobenzene−hydrogenation and halobenzene−amination. Under a hydrogen atmosphere, the supported Pd catalyst exhibits significant activity in phenol amination with various amines, but the selectivity to primary aniline is poor.
