The title compound, C(9)H(10)N(4)S·0.095H(2)O, consists of discrete 4-ethyl-3-(3-pyrid-yl)-1H-1,2,4-triazole-5(4H)-thione mol-ecules and a disordered mol-ecule of water of hydration with partial occupancy, lying on a twofold rotation axis. The dihedral angle between the pyridine and triazole rings is 41.73 (8)°. In the crystal structure, mol-ecules are hydrogen bonded via triazole NH groups and...
A series of 2-((arylamino)methyl)-5-(3-methoxyphenyl)-1-phenyl-1H-1,2,4-triazole-3-thione derivatives have been synthesized and characterized by FT-IR, NMR, mass spectral and elemental analysis. Compounds (MM4a-m) have been evaluated for their in vitro antibacterial activity against selected gram-positive and gram-negative bacteria and in vitro antifungal activity against fungal pathogens by us...
In this research, one-pot three-component synthesis of 3,4-dihydropyrimidin-2-(1H)-ones havebeen developed using Biginelli reaction from the interaction between ethyl/methyl acetoacetate,aromatic aldehydes, and urea/thiourea in the presence of 4-sulfobenzoic acid as a new, effective,inexpensive, and available bronsted acid. Avoidance of toxic and dangerous solvents, easy isola...
Crystal structure of bis(3,4,6-tetrahydropyrimidine-2(1H)thione-S)gold(I) chloride, [Au(C4H8N2S)2]Cl
Schiff base derivatives are some of the most widely used organic compounds for industrial purposes and they exhibit a broad range biological activities. In this paper, new derivative (2) synthesized from condensation reaction 1-amino-5-benzoyl)-4- phenylpyrimidine-2(1H)-thione (1) with 2-chlorobenzaldehyde. The compound was characterized by 1H, 13C NMR, FT-IR. activity property tested against t...
A magnetic nanoparticle conjugated mesoporous nanocatalyst (Fe(3)O(4)@mesoporous SBA-15) with a high surface area has been synthesized by chemical conjugation of magnetite (Fe(3)O(4)) nanoparticles with functionalized mesoporous SBA-15. Functionalized mesoporous SBA-15 containing surface carboxyl and amino groups was synthesized via the thiol-ene click reaction of cysteine hydrochloride and vin...
