IONIC STRUCTURE AND CONDUCTIVITY, TUNABLE HYDROPHOBICITY AND VERY LOW VOLATILITY ARE THE PROPERTIES OF ROOM TEMPERATURE IONIC LIQUIDS (RTIL) THAT MAKE THEM ATTRACTIVE FOR ELECTROCHEMICAL APPLICATIONS. 1 BUT THE SLOW MASS TRANSFER IS KNOWN AS THEIR DISADVANTAGE. IN THIS RESPECT, IMMOBILIZATION OF RTIL ON THE ELECTRODE SURFACE REPRESENTS A SUITABLE ALTERNATIVE APPROACH. HEREIN, A MODIFIED ELECTRODE WITH ORDERED MESOPOROUS SILICA THIN FILM HAS BEEN CONSTRUCTED FOR IMMOBILIZATION OF IONIC LIQUIDS. THE DESIRED SILICA NANOSTRUCTURE WAS DEPOSITED ON THE ELECTRODE USING AN ELECTROCHEMICAL ETHOD KNOWN AS ELECTROCHEMICALLY ASSISTED SELF-ASSEMBLY. 2 TEM ANALYSIS SHOWED THAT THE DESIRED SILICA FILM HAS UNIFORM THICKNESS WITH ALIGNED AND ACCESSIBLE MESOCHANNELS TO THE ELECTRODE SURFACE. THE POSSIBILITY OF THE IMMOBILIZATION OF 1-HEXYL-3-METHYLIMIDAZOLIUM IODIDE AND 1-HEXYL-3-METHYLIMIDAZOLIUM TRIIODIDE AS TWO IONIC LIQUIDS BEARING ELECTROACTIVE ANIONS HAVE BEEN STUDIED BY VOLTAMMETRIC ANALYSIS. THE RESULTS CLEARLY DEMONSTRATE THE ADSORPTION OF POSITIVELY CHARGED IMIDAZOLIUM IONS INSIDE THE NEGATIVELY CHARGED SILICA MESOCHANNELS. THIS FAVORABLE ELECTROSTATIC INTERACTION SIMPLY LEADS TO THE ADSORPTION OF IODIDE OR TRIIODIDE AND THEN IMMOBILIZATION OF THE DESIRED ELECTROACTIVE IONIC LIQUIDS. EFFECT OF THE SUPPORTING ELECTROLYTE AND THE ANIONS OF IONIC LIQUIDS WERE EXAMINED ON DURABILITY AND LEACHING STABILITY OF THE ELECTRODES. THE TRIIODIE BASED IONIC LIQUID HAS EXTRAORDINARY STABILITY IN THE PRESENCE OF VARIOUS TYPES AND CONCENTRATIONS OF SUPPORTING ELECTROLYTES AND AFTER 5 HOURS THE ELECTRODE SHOWED MORE THAN 30% OF THE INITIAL CURRENTS.

COMPOUNDS WITH IMIDAZOLE RING SYSTEM HAVE MANY PHARMACOLOGICAL PROPERTIES AND CAN PLAY IMPORTANT ROLE IN BIOCHEMICAL PROCESSES.1 FOR EXAMPLE, IT IS REPORTED THAT SUBSTITUTED IMIDAZOLES CAN ACT AS GLUCAGON RECEOTOR ANAGONISTS, INHIBITORS OF P38 MAP KINASE, B-RAF KINASE, PLANTS GROWTH REGULATORS, ANTIBACTERIAL, ANTITUMOUR, THERAPEUTIC AGENTS AND ALSO PESTICIDE. RECENT DEVELOPMENT IN THE DIHYDROPYRIDINES CHEMISTRY AND OUR CONTINUED INTEREST IN THE DEVELOPMENT OF EFFICIENT AND ENVIRONMENTALLY FRIENDLY PROCEDURE FOR THE SYNTHESIS OF PHARMACEUTICAL COMPOUND2-4 TRIGGERED US TO DESCRIBE HERE THE NOVEL METHOD FOR THE SYNTHESIS OF BENZOIMIDAZOLES IN THE PRESENCE OF SYNTHESIZED IONIC LIQUID (SCHEME 1)…

XANTHENE DERIVATIVES ARE IMPORTANT HETEROCYCLIC COMPOUNDS BECAUSE OF THEIR USEFUL BIOLOGICAL AND PHARMACOLOGICAL PROPERTIES SUCH AS ANTIVIRAL, ANTIBACTERIAL AND ANTI-INFLAMMATORY ACTIVITIES. THESE COMPOUNDS ARE ALSO USED AS DYES, AS LUMINESCENT SENSORS, IN LASER TECHNOLOGIES, IN FLUORESCENT MATERIALS FOR THE VISUALIZATION OF BIOMOLECULES AND IN PHOTODYNAMIC THERAPY [1].IN CONTINUATION OF OUR ONGOING STUDIES TO SYNTHESIZE OF HETEROCYCLIC AND PHARMACEUTICAL COMPOUNDS AT MILD AND PRACTICAL PROTOCOLS [2], HEREIN WE WISH TO REPORT OUR EXPERIMENTAL RESULTS ON THE SYNTHESIS OF DI INDOLYLMETHANES USING DIFFERENT BENZALDEHYDES AND B-NAPHTOL IN THE PRESENCE OF IONIC LIQUID. ALL OF SYNTHESIZED COMPOUNDS WERE CHARACTERIZED BY IR AND NMR.

IN THE PAST DECADE, DIHYDROPYRIMIDINONES (DHPMS) AND THEIR DERIVATIVES HAVE ATTRACTEDCONSIDERABLE INTEREST BECAUSE THEY ARE COMMERCIALLY USED AS CALCIUM CHANNEL BLOCKERS, ANTIHYPERTENSIVE AGENTS, Α-1A-ANTAGONISTS AND NEUROPEPTIDE Y (NPY) ANTAGONISTS. THEY ALSO EXHIBIT ACTIVITIES SUCH AS ANTIFUNGAL, ANTIVIRAL, ANTICANCER, ANTIBACTERIAL AND ANTI-INFLAMMATORY AGENTS [1].IN CONTINUATION OF OUR ONGOING STUDIES TO SYNTHESIZE OF HETEROCYCLIC AND PHARMACEUTICAL COMPOUNDS AT MILD AND PRACTICAL PROTOCOLS [2], HEREIN WE WISH TO REPORT OUR EXPERIMENTAL RESULTS ON THE SYNTHESIS OF DIINDOLYLMETHANES USING DIFFERENT BENZALDEHYDES AND ETHYLACETOACETATE, UREA IN THE PRESENCE OF IONIC LIQUID. ALL OF SYNTHESIZED COMPOUNDS WERE CHARACTERIZED BY IR AND NMR.

EXTRACTIVE DESULFURIZATION (EDS) IS ONE OF THE MORE REGARDED TECHNIQUE FOR THE REMOVAL OF SULFUR COMPOUNDS (PRESENT IN THE LIQUID FUEL) WHICH PRODUCE ONE OF THE MAIN SOURCE OF AIR POLLUTIONS I.E. SOX. ENVIRONMENTAL CONSIDERATIONS LIMIT THE USE OF ORGANIC SOLVENTS TO THIS PROCESS. IONIC LIQUIDS HAVE UNIQUE PROPERTIES WHICH CAUSE INCREASE THE APPLICATION OF THESE TYPE OF SOLVENTS FOR EDS. IN CONTINUATION OF OUR PREVIOUS STUDY ON THE APPLICATION OF TASK-SPECIFIC PHOSPHONIUM IONIC LIQUIDS (PIL) FOR EDS. TRI-N-BUTYL-(2- HYDROXYETHYL) PHOSPHONIUM BROMIDE ([TBHEP][BR]) PERFORMANCE OF EDS AS A PIL CONTAINING ALCOHOL MOIETY WAS STUDIED. ...
