N-(4-acetylphenyl)-N′-(2-nitrobenzoyl)-thiourea has been synthesized in high yield under PEG-400 as the phase-transfer catalyst and its the compound structure was determined by single crystal X-ray diffraction. The compound is also a considerable plant-growth regulator. In addition, the compoundLexhibited selective recognition for Hg2+over other metals ions such as Ag+, Ca2+, Co2+, Ni2+, Cd2+, Pb2+, Zn2+, Cr3+, and Mg2+in DMSO solutions. [ABSTRACT FROM PUBLISHER]

The complex bis(μ-sulfur)-sulfur-[N-phenyl-N'-(2-nitrobenzoyl)-thiourea]copper (I) was obtained from the reaction between the N-phenyl-N'-(2-nitrobenzoyl)-thiourea(HL) and copper(II). The compound was characterized by IR and 1H NMR, 13C NMR spectroscopy and its structure was determined by single crystal X-ray diffraction. The complex is binuclear with two copper(I) ions coordinated by a terminal sulfur, two bridging sulfurs, and a HL molecule. In addition, the compound is also a considerable plant-growth regulator.

A series of N-aryl-N′-(4-ethyloxybenzoyl)-thiourea 3a–h was synthesized under phase transfer catalysis and r.t. conditions. The chemical structure of all compounds were established by IR, 1H NMR, and 13C NMR studies, and all of the compounds were investigated for plant-growth regulating activity. Excitingly, they remarkably enhance root elongation. [ABSTRACT FROM AUTHOR]
