Reaction of 5-phenyl tetrazole with ethyl chloroacetate to form ethyl (5-phenyl-1H-tetrazol-1-yl) acetate (1). Compound 1 react with hydrazine hydrate in ethanol yield 2-(5-phenyl-1H-tetrazol-1-yl) acetohydrazide (2). The condensation of (2) with various aldehydes yield the corresponding substituted N'-[-arylidene]-2-(5-phenyl-1H-tetrazol-1-yl) acetohydrazide (3a- j). Th...

Reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-SiO2/HClO4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1H-pyrazol-5-ol derivatives in high yields.

2-Phenyl-1-(3?,5?-dichloro-2?-benzo(b)thiophenoylamino)-4-arylidine-5-imidazolones (2a-j) were prepared from the 2-hydrazinocarbonyl-3,5-dichlorobenzo[b]thiophene 1 by the reaction with different oxazolinone which were prepared by the condensation of substituted benzaldehyde with benzoyl glycine in presence of sodium acetate and acetic anhydride. Reaction of 1 with different aromatic isothiocya...

In the crystal structure of the title compound, C(15)H(15)NO, the two benzene rings are twisted from each other by a dihedral angle of 47.97 (4)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, and π-π inter-actions with a centroid-centroid distance of 3.8493 (5) Å are observed.

proline and glycine betaine are the most common compatible solutes that prevent plants from destructive effects of osmotic stresses by osmotic adjustment and protection of membranes, proteins and enzymes. it has been reported that exogenous application of these compounds, can increase plant resistance to drought stress. therefore a factorial experiment based on randomized complete block design ...
