Hydrolysis Rate of Functionalized Fullerenes Bearing Alkoxysilanes: A Comparative Study

Abstract

Soluble fulleropyrrolidines bearing a trialkoxysilyl functionality (methoxy, ethoxy, butoxy, and isopropoxy) have been prepared and characterized. The hydrolysis rate constant for each fulleropyrrolidine was measured with 1 H NMR spectroscopy by following the disappearance of selected resonances of the fullerene substrate under the conditions (HCl/ H 2 O/THF) used for the preparation of fullerene-doped solgel glasses. It has been found that fulleropyrrolidine 1, bear-

A family of silatrane‐armed triazole‐encapped salicylaldehyde‐derived Schiff bases: Synthesis, spectral analysis, and antimicrobial and quantum chemical evaluation

“…Propargyl bromide (80% in toluene; Aldrich), hydrazine hydrate, ethylenediamine, o ‐aminophenol, potassium carbonate (Thomas), sodium sulfate (Finar), 3‐chloropropyltriethoxysilane (Aldrich) and Bromotris(triphenylphosphine)copper(I) (CuBr(PPh 3 ) 3 ) (Aldrich) were used as received. Schiff bases and 3‐AzPTES were synthesized using known procedures from the literature . Infrared (IR) spectra were obtained neat with a Thermo Scientific Fischer spectrometer.…”

“…3-Azidopropyltriethoxysilane was synthesized by the known procedure. 13 3-Chloropropyltrietho xysilane (ClPTES) (Aldrich), N-(2-aminoethyl)-3-aminopropyltrimet hoxysilane (Aldrich), 3-aminopropyltrimethoxysilane (APTMS) (Aldrich), 3-mercaptopropyltrimethoxysilane (MPTMS) (Aldrich) and triethanolamine (Merck) were used directly as received. Melting points were measured in a Mel Temp II device using sealed capillaries.…”

“…The methoxy and ethoxy groups of the silanes are replaced by the atranyl moiety (OCH 2 CH 2 ) 3 N, which consists of two triplets due to NCH 2 (2.69-2.81) and OCH 2 (3.64-3.81) protons. In the 13 The data represented an average of three replicates (± SD). Different letters indicate significant differences between treatments at P ≤ 0.05.…”

Synthesis and Immobilization of Benzothiazole‐Appended Triazole‐Silane: Biological Evaluation and Molecular Docking Approach

“…"Click" chemistry is preferred to insert a triazole linker between two subsequent units having a great significance in formation of new biomaterials with unique physical and chemical properties. [8][9][10][11][12][13][14][15] In 1,4-disubstituted 1,2,3-triazole, high dipole moment make it hydrogen bond acceptor and attribute to binding ability towards biological sites and improving properties. Benzothiazole and triazole based derivatives also showed inhibitory activity due to interaction of electron rich heteroatoms with active site of various enzymes.…”
