Polarographic Studies on Heterocyclic Compounds. II. Saponification of Isonicotinic Acid Methyl Ester

Preparation and Reactions of Heterocyclic Compounds II

Commercial preparation of furan proceeds by way of the aldehyde, furfural, which in turn is generated from pentose containing raw materials like corncobs, as shown in the uppermost equation below. Similar preparations of pyrrole and thiophene are depicted in the second row equations. Equation 1 in the third row illustrates a general preparation of substituted furans, pyrroles and thiophenes fro...

A saponification-triggered gelation of ester-based Zn(II) complex through conformational transformations.

Novel saponification-triggered gelation in an ester-based bis-salen Zn(II) complex (1) is described. Strategic structural modifications induced by NaOH in 1 tune the dipolar-/π-interactions leading to J-aggregation and the creation of an inorganic gel material (IGM), which has been established by photophysical, DFT and rheological studies.

The Kinetic and Thermal Degradation Studies of N-(4-Acetyl-phenyl)-acetimidic Acid Pyridine-3-yl ester Metal(II) Complexes

Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. Th...

Azo-hydrazo Tautomerism: Further Evidence Based on Polarographic Reduction and Acidity Function of Some Heterocyclic Compounds Containing

Potentiometric pKa and polarographic behaviour of I ,3-indandione-monoxime-2-phenyl azo and four of its substituted derivatives were investigated in buffer solution of pH -2-12. The results showed that the compounds are in the azo-form, where its reduction wave precedes that of the oxime. A mechanism for the electrodic processes was proposed. Half-wave potentials showed fair correlation with Ha...
