in this research, an efficient synthesis toward 2-(2-((4-methoxybenzoyl)imino)-4-(4-methoxyphenyl)thiazol-3(2h)-yl)-2-phenylacetic acid via a three-component tandem reaction using aroylisothiocyanate, phenyl glycine, and 4-methoxyphenacyl bromide in an ionic liquid (il) has been described. 1-methyl-3-pentylimidazolium bromide (il) has been employed as a recyclable green solvent. the work-up pro...

The effect of the presence of titanium dioxide in two new imines, (E,E)-(butane-1,4-diyl)bis(oxybutane-4,1-diyl) bis(4-{[(benzo[d][1,3]thiazol-2-yl)methylidene]amino}benzoate) (SP1) and (E)-N-[(benzo[d][1,3]thiazol-2-yl)methylidene]-4-dodecylaniline (SP2), on the properties and stability of imine:TiO2 composites for organic device applications were examined. The investigated titanium dioxide (i...

Ylideneamine functionalised heterocyclic ligands, 1,3-dimethyl-1,3-dihydro-benzimidazol-2-ylideneamine (I), 3-methyl-3H-benzothiazol-2-ylideneamine (II) or 3,4-dimethyl-3H-thiazol-2-ylideneamine (III), were employed in the preparation of a series of both charged and neutral gold(I) complexes consisting either of a Au(C(6)F(5)) fragment (1-3), a [Au(PPh(3))](+) unit (4-6) or a [Au(NHC)](+) unit ...

We discovered a 1,3-dipolar species co-existing in two different structures. Photolysis of matrix-isolated 5-phenyltetrazole generates two forms of phenylnitrile imine: propargylic and allenic. They are not resonance structures but correspond to different energy minima, representing bond-shift isomers. These distinct species were characterized spectroscopically and confirmed by calculations up ...

A new iridium catalyst containing an imine-diphosphine ligand has been developed, which showed high efficiency for the hydrogenation of CO2 to formate (yield up to 99%, TON up to 450 000). A possible catalytic mechanism is proposed, in which the imine group of the catalyst plays a key role in the cleavage of H2 and the activation of CO2.

The facile regioselective synthesis of the P(iii) substituted thiazol-2-thione 2 is presented. Reaction of 2 with hydrogenperoxide-urea, elemental sulfur and selenium resulted in P(v) chalcogenide thiazol-2-thiones 3-5. All compounds were characterized using (31)P, (1)H, (13)C NMR, IR and elemental analyses and, additionally, by the single-crystal X-ray diffraction technique. Oxidative desulfur...

The catalysis by S, 1 0, IS,20-tetrakis(pentafluorophenyl)-21H,23H-porphyrin iron(III) chloride (F20 TPPFeCl) of alkene epoxidation by H20 2 has been investigated. Extensive catalyst decomposition was observed during the reaction. A kinetics and product yield analysis has shown that this decomposition does not occur via either the oxoperferryl intermediate (F 20 TPP·+)F e =0 or the oxoferryl in...
