A new 3,3 0 -dibenzoyl-1,1 0 -propan-1,3-diyl)bisthiourea was synthesized by using benzoylisothiocyanate with 1,3-diaminopropane in aprotic solvent. The structure was determinated by means of FT-IR, 1 H-NMR, 13 C-NMR and mass spectroscopic techniques. The crystal structure of 3,3 0 -dibenzoyl-1,1 0 -(propan-1,3-diyl)bisthiourea has also been examined by using X-ray crystallographic techniques and found to be crystallized in the monoclinic space group P2 1 /c with the unit cell parameters: a = 5.968(1) Å , b = 19.471(2) Å , c = 16.585(2) Å , b = 98.32(1)°, V = 1907.0 (4) Å 3 , Dx = 1.395 g cm -3 , and Z = 4 respectively.

New aroyl thioureas; N-nicotinoyl-N'-(4-nitrophenyl) thiourea (3a) and N-nicotinoyl-N'-(2-nitrophenyl) thiourea (3b) were synthesized and studied as anion-binding receptors. Upon adding tetrabutyl ammonium halides (fluoride, chloride bromide and iodide), cyanide and hydroxide ions to their solutions in DMSO respectively, the colour of the solutions has shown striking changes from pale yellow to brillant yellow or red. The binding effects of the anions were investigated by UV-VIS spectroscopic method and 1 H NMR titrations.

Pyridinium fluorochromate supported on TriSyl silicas was prepared by co-adsorption. The supported reagent was used in equimolar quantity to oxidise some organic compounds with good yields and complete selectivity. These procedures are mild, efficient, safe and the work-ups are very convenient. .

The title compound, bis[4 (3' benzoyl)thiocarbamidophenyl]ether, was synthesized by the reac tion of benzoylisothiocyanate with 4,4' diaminodiphenylether in aprotic solvent. The structure was determi nated by means of elemental analysis and FT-IR, 1 H-NMR, 1 3C-NMR and MS spectroscopic techniques. The crystal structure was characterized by X ray syngle crystal analysis: orthorhombic, sp. gr. Pnna, Z = 4. In crystal packing, there are intramolecular hydrogen bond N-H⋅⋅⋅O generating S(6) motif, and intermolecular hydrogen bond N-H⋅⋅⋅S forming (8) ring.
