A highly efficient one-pot three-component protocol was devised for the synthesis of novel derivatives ((phenylethlidene)hydrazinyl)thiazol-4(5H)one by reaction acetophenone derivatives, ethyl chloroacetate and thiosemicarbazide, in ethanol at room temperature presence copper supported hydroxyapatite-encapsulated-γ-Fe2O3 (γ-Fe2O3@HAp@CPTMS@AT@Cu(ӀI)) as new magnetically recyclable heterogeneous...

New complexes of trivalent cobalt with substituted thiosemicarbazone ligands having an NNS donor system {HL1 = 4-(4-nitrophenyl)-1-((pyridin-2-yl)methylene)thiosemicarbazide and HL2 4-(2,5-dimethoxyphenyl)-1-((pyridin-2-yl)methylene)thiosemicarbazide} were synthesized via the in situ oxidation divalent chloride accompanying its addition to ligands. The C1 C2 characterized elemental (CHNS) analy...

In the title complex, [Ni(C16H15N3O2S)(C18H15P)], the Ni(II) atom has a distorted tetra-hedral coordination geometry, comprised of N, S, O and P atoms of the tridentate thiosemicarbazide ligand and the P atom of the triphenylphosphane ligand. The benzene ring makes a dihedral angle of 53.08 (11)° with the phenyl ring of the phenyl-thio-semicarbazide moiety and dihedral angles of 73.69 (11), 20....

A convenient synthesis for 1,3,4-thiadiazolyl quinazolinone derivatives is described via facile cyclization of anthranilic acid with succinic anhydride and upon reaction glycine afforded 3-glycinyl derivative (2), which then treated thiosemicarbazide produced (3). Also, the key intermediate isothiocyanatobenzoazinone (13) synthesized checked triazolyl-(14), oxooxazolidinyl-(15) triazinanyl-(16a...
