Solid state Acid–Base Reactions of Arylamino Nicotinic Acids: X-ray Crystal Structures of Salts
Abstract: 2-(Phenylamino)nicotinic acid (PNA), 2-(methyl(phenyl)amino)nicotinic acid (MPNA), 2-(p-tolylamino)nicotinic acid (TNA) and 2-(methyl(p-tolyl)amino)nicotinic acid (MTNA) are the ampholites which were synthesized by the coupling of respective aryl amines and 2-chloronicotinic acid in the presence of p-tolylsulfonic acid and pyridine. All these molecules were crystallized in different solvents to obtain intra and intermolecular proton transferred adducts in the solid state. TNA is an only compound which has under gone intra (zwitterion) and intermolecular …
