Abstract
Abstract The 13 C NMR spectra of several 1,3-pyridylmethyl ureas and their corresponding thioureas have been obtained. The 13 C chemical shifts, and the direct and long range 13 C 1 H coupling constants have been deduced. The results indicate an E, Z molecular conformation for 1,3-pyridylmethyl ureas and thioureas which is stabilized by internal NH⋯N (pyridine) hydrogen bonding.
