Four new 1,5-benzothiazepines were synthesized by reaction of o-aminothiophenol with curcumin and curcuminoid β-diketones, in methanol acetic acid. The mechanism involves a Michael addition on the CC double bond affording benzothiazepine two pendant groups, an aryl group adjacent to sulfur atom 1-phenylethanone NH seven membered ring. 1D 2D multinuclear NMR (1H, 13C, 15N, 119F) solution 13C 15N...

A new Schiff base 2-aminothiophenol furfural self assembled monolayer (SAM) has been fabricated on a bare gold electrode as a novel sensor for determination of dopamine. Electrochemical impedance spectroscopy was utilized to investigate the properties of the Au 2-aminothiophenol furfural self assembled monolayer modified electrode (Au ATF SAM-ME) using the [Fe(CN)6] 3-/4redox couple. The electr...

The expeditious synthesis of 2-aryl-benzothia/(oxa)zoles was carried out by the condensation of 2-aminothiophenol/2-aminophenol and diverse aryl aldehydes in presence of Acacia concinna as a biocatalyst under microwave irradiation. The catalytic process is associated with excellent yields, greener reaction conditions and the environmentally friendly microwave technique which are the st...

A series of new 6-amino-4aryl-2’-[(4-Aminophenyl)thio]-2,4’-bipyridine-5-carbonitriles (3a-h) were synthesized from 4-aminothiophenol (1). The reaction of 4-aminothiophenol with 4-acetyl-2-chloropyridine yielded 1-{2-[(4-aminophenyl)thio]pyridin-4-yl}ethanone(2).Furthertreatment of  2 with aromatic aldehydes in the presence of alcoholic malanonitrile in ammonium acetate gave compounds (3a-h). T...

Dense two-dimensional assemblies of silver nanoparticles were fabricated over vast areas (~19 cm(2)) by utilizing a simple liquid-liquid interface assembly technique. The Raman signal for p-aminothiophenol immobilized on the assemblies was drastically enhanced by plasmon coupling-induced hot spots, and the enhanced signal showed high spatial reproducibility.

9, 10-Phenanthrenequinone (PQ) is regarded as a harmful environmental pollutant and its presence has been reported in atmospheric environment. The measurement of PQ in environment should be necessary to evaluate the influence of PQ on human health. We found that PQ reacted with 2-aminothiophenol under acidic condition to form fluorescent derivative which emits green fluorescence at 510nm. Based...

The study of biologically active inorganic compounds has led to the development of several important chemotherapeutic drugs in the past few decades, the most notable example of which is cis-[PtCl2(NH3)2] (cis-DDP).1 In addition to compounds of platinum, many other transition metal complexes have been found to exhibit considerable antineoplastic activities, including those of general formulae Rh...
