We used cold atmospheric pressure plasma jet to examine in detail 1O2 generation water. ESR with 2,2,5,5-tetramethyl-3-pyrroline-3-carboxamide, a secondary amine probe, was for the detection of 1O2. Nitroxide radical formation detected after irradiation 2,2,5,5-tetramethyl-3-pyrroline-3-carboxamide solution. An scavenger/quencher inhibited signal intensity induced by irradiation, but this inhib...
Two thiourea and urea based indole conjugated ligands show selective color changes with fluoride along with an absorbance band at 936 nm and 904 nm respectively.

Erratum to “Synthesis, characterization and crystal structure of platinum(II) complexes with thiourea derivative ligands” [Eur. J. Chem. 9 (4) (2018) 360-368].
Functionalized chiral tetrahydroquinolines were synthesized through supramolecular organocatalysis using quinidine-NH-thiourea 3c/L-phenylalanine 4i followed by reductive amination from the simple substrates.
New chiral bifunctional thiourea-phosphonium salts have been developed based on natural amino acids as highly efficient phase-transfer catalysts in the enantioselective aza-Henry reaction.
