2-aminopyridinium benzoate.

Synthesis, Growth and Characterization of Nonlinear Optical Bis(2-aminopyridinium) Sulfate Single Crystals

A second polymorph of 2-aminopyridinium dihydrogenphosphate.

In the title compound, beta-C5H7N2+.H2PO4-, the tetrahedral dihydrogenphosphate moieties are linked into double chains by O-H...O hydrogen bonds, and the organic species crosslink the chains into sheets by way of N-H...O bonds. The resulting structure is quite different from that of the previously described alpha polymorph of this stoichiometry [Czapla, Dacko & Waskowska (2003). J. Phys. Conden...

Helical chiral 2-aminopyridinium ions: a new class of hydrogen bond donor catalysts.

Helical chiral 2-aminopyridinium ions were designed as a significantly more acidic (active) dual hydrogen-bonding catalyst than commonly used (thio)urea-based systems. The helicene framework was specifically utilized to position an inherently chiral barrier on the hydrogen-bonding side of the catalyst. The catalyst reactivity and enantioselectivity were successfully demonstrated in additions of...

Effects of emamectin benzoate combined with acetamiprid, eforia and hexaflumuron against Tuta absoluta (Lep.: Gelechiidae)

Tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most destructive pests of tomato in many parts of the world including Iran. The toxicity of emamectin benzoate alone and combined with acetamiprid, eforia (thiamethoxam + lambda-cyhalotrin) and hexaflumuron was evaluated against 2nd instar larvae of Tuta absoluta (Meyrick) under 25 ± 1 °C, the relative humidity of ...

Synergistic Influence of Benzoate Ions on Inhibition of Corrosion of Mild Steel in 0.5m Sulfuric Acid by Benzotriazole

The influence of benzoate anions on the corrosion inhibition effect of benzotriazole (BTA) for mild steel in sulfuric acid has been investigated. The investigation was carried out by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The addition of benzoate ions greatly enhances the inhibition efficiency of BTA in a synergistic manner. This effect has bee...
