“…[23] Tin amalgam was prepared by dissolving tin metal in liquid mercury. [24] 3,6-di-tertbutyl-o-quinone, [25] 2,6-dimethyl-N-(2-pyridylmethylene)aniline, [26] N-(2-pyridylmethylene)benzene-1,4-diamine, [27] 4-nitro-N-(2pyridylmethylene)benzenamine, [28] N-(4-[2-phenyldiazenyl]phenyl)-N-(2-pyridinylmethylidene)amine [29] and 1,4-di-isopropyldiazadiene-1,3, 1,4-di-tert-butyldiazadiene-1,3, 1,4di-cyclohexyldiazadiene-1,3, 1,4-di-adamantyl-diazadiene-1,3 [30] were synthesized according to literature procedures. The synthesis of bis(3,6-di-tert-butylcatecholato)tin(IV) etherate (Cat 2 Sn(Et 2 O) 2 ) was performed by reduction of 3,6-di-tert-butyl-o-quinone with an excess of tin amalgam in diethyl ether according to the previously published procedure.…”

A series of new octahedral bis‐3,6‐di‐tert‐butylcatecholates based on tin(IV) containing metal‐coordinated N‐donor ligands (substituted iminopyridines and diazabutadienes) has been synthesized and structurally characterized. The compounds, both solid and in solution, are intensely colored. They absorb in the visible region of the spectrum. Charge transfer between the catecholate donor and the diimine acceptor is responsible for the absorption. This observation is in good agreement with the DFT calculations and with the electrochemical studies carried out by CV.

“…A Schiff base was derived from 4-E-2-phenyldiazenylaniline and pyridine-2carboxaldehyde (Figure 55) and investigated for its cation recognition ability. The schiff base was found to be highly sensitive and selective for sensing of Ag + ions and Cd +2 ions and could act as chemosensor for the detection of Ag + and Cd +2 in presence of other interfering ions [81].…”

Pyridine is a valuable nitrogen based heterocyclic compound which is present not only in large number of naturally occurring bioactive compounds, but widely used in drug designing and development in pharmaceuticals as well as a precursor to agrochemicals and chemical-based industries. Pyridine derivatives bearing either formyl or amino group undergo Schiff base condensation reaction with appropriate substrate and under optimum conditions resulting in Schiff base as product which behave as a flexible and multidentate bioactive ligand. These Schiff bases are of great interest in medicinal chemistry as they can exhibit physiological effects similar to pyridoxal-amino acid systems which are considered to be very important in numerous metabolic reactions. They possess an interesting range of bioactivities including antibacterial, antiviral, antitubercular, antifungal, antioxidant, anticonvulsants, antidepressant, anti-inflammatory, antihypertensive, anticancer activity etc. and considered as a versatile pharmacophore group. Further, several pyridine-based Schiff bases show very strong binding abilities towards the various cations and anions with unique photophysical properties which can be used in ion recognition and they are extensively used in development of chemosensors for qualitative and quantitative detection of selective or specific ions in various kinds of environmental and biological media. These chapter insights the bioactivity and ion recognition ability of Schiff bases derived from pyridine derivatives.
