Three types of amines were studied to establish a match mismatch effect for structurally diverse acid analytes. Single-crystal X-ray diffraction analysis was performed on the diastereomeric salts of roof shape amines and both isomers of mandelic acid to establish molecular conformation and correlate the absolute configuration with the observed NMR shift. The present system also recognizes the two isomers of weakly acidic BINOL and its derivatives.</p>1 aGupta, Riddhi1 aGonnade, Rajesh, G.1 aBedekar, Ashutosh, V.  uhttps://library.ncl.res.in/content/application-roof-shape-amines-chiral-solvating-agents-discrimination-optically-active-acids
