Abstract
A study was made of the PMR spectra of heterocyclic analogs of chalcone containing thiazole, imidazole, benzofuran, and pyridine residues. The shift patterns were determined of the signals under the influence of an aromatic solvent. Through experiments made on the Overhauser homonuclear effect the signals were reliably assigned and the orientation of the heterocyclic fragments in the molecules of chalcones was established.
