THE MOLECULAR-STRUCTURE OF SOME UREA AND THIOUREA DERIVATIVES

The molecular structures for N-phenyl-N'-acetylurea, N-phenyl-N'-capro nylthiourea, and N - phenyl - N' - benzoyl thiourea have been characte rized by X-ray diffraction and NMR spectroscopy. The relative position s of atoms in the parent molecular fragment, common to all three analy zed compounds, are discussed. (C) 1998 Elsevier Science B.V.
