ジアルキルアミノフェニル基を有するチオウレア誘導体の合成・構造解析および結晶構造
Two thiourea derivatives, N,N'-bis[2-(dimethylamino)phenyl]thiourea and N,N'-bis[2-(diethylamino)phenyl]thiourea, were obtained by reacting 1,1'-thiocarbonyldiimidazole with two equivalents of the corresponding 2-amino-N,N-dialkylaniline. X-ray crystallographic analysis revealed intramolecular hydrogen bonding between the thiourea N-H groups and the dialkylaminophenyl nitrogen atoms. The remaining N-H bonds participate in intermolecular interactions with sulfur atoms of C=S groups in neighboring molecules within the crystal packing. Spectroscopic characterization by NMR and IR confirmed the structural assignments derived from crystallography.
The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
