(MDPI, ST ALBAN-ANLAGE 66, 2005)
Iminoester hidroklorürler 1 sentezlenmiştir. Bu bileşikler daha sonra ester etoksikarbonil hidrazonlar 2'ye dönüştürüldü ve bunlardan sırasıyla yeni bir ikame edilmiş 4-amino-4,5-dihidro-lH-1,2,4-triazol-5-onlar, 3 serisi ...
N-H?N and C-H?? interactions in 4-amino-3-methyl-5-(p- tolyl)-4H-1,2,4-triazole and 4-amino-3-methyl-5-phenyl-4H-1,2,4-triazole
(2006)
The title compounds, C10H12N4, (I), and C9H10N4, (II), have been synthesized and characterized both spectroscopically and structurally. The dihedral angles between the triazole and benzene ring planes are 26.59 (9) and ...
Microwave-assisted synthesis and characterization and theoretical calculations of the first example of free and metallophthalocyanines from salen type Schiff base derivative bearing thiophen and triazole heterocyclic rings
(Elsevier, 2007)
Novel metal-free and metallophthalocyanine complexes of Co, Ni, Cu, and Zn have been synthesized by exposure to microwave irradiation and reflux conditions and the products purified by several techniques. The newly prepared ...
Synthesis of some N-alkoxycarbonyl-N"-benzoyl-benzamidrazones(p- toluamidrazones) and 1,3,5-trisubstituted 1,2,4-triazole derivatives from N-benzoylimidates and their antimicrobial and anticancer screening studies
