Imidazole Structure thiab Properties

 

Imidazole yog monoacidic puag muaj peev xwm tsim crystalline ntsev nrog acids. Lub melting point ntawm tus naj npawb ntawm cov yam ntxwv imidazolium ntsev. Imidazole yog ib tug 5-vaj huam sib luag lub nplhaib, uas yog soluble nyob rau hauv dej thiab lwm yam polar solvents. Nws muaj nyob rau hauv ob daim ntawv sib npaug Tautomeric, 1H-imidazole thiab 3H-imidazole, vim hais tias cov hydrogen atom tuaj yeem nyob ntawm ob qho ntawm ob lub nitrogen atoms. Imidazole yog ib qho polar compound zoo heev, raws li pom los ntawm kev suav dipole ntawm 3.61D, thiab yog soluble nkaus hauv dej. Lub compound yog cais raws li aromatic vim muaj ib tug sextet ntawm p-electrons, muaj xws li ib tug khub ntawm electrons los ntawm lub protonated nitrogen atom thiab ib tug los ntawm ib tug ntawm tag nrho cov seem ntawm plaub atoms ntawm lub nplhaib.

Reactivity ntawm Imidazole

 

Imidazole tuaj yeem suav hais tias muaj cov khoom zoo ib yam li pyrrole thiab pyridine. Cov electrophilic reagent yuav tawm tsam cov tsis sib koom electron khub ntawm N-3, tab sis tsis yog ntawm "pyrrole" nitrogen vim nws yog ib feem ntawm thearomatic sextet. Thaum lub nplhaib imidazole yog qhov yooj yim rau electrophilic nres ntawm annular carbon, nws yuav tsis tshua muaj kev koom tes hauv nucleophilic hloov cov tshuaj tiv thaiv tshwj tsis yog tias muaj cov hluav taws xob muaj zog tshem tawm lwm qhov ntawm lub nplhaib. Nyob rau hauv qhov tsis muaj qhov ua kom ua rau txoj haujlwm feem ntau cuam tshuam rau nucleophilic nres yog C-2. Lub nplhaib fused benzene hauv Benzimidazole muab cov hluav taws xob txaus nrog rub kom tso cai rau ntau yam nucleophilic hloov cov tshuaj tiv thaiv ntawm C-2.

Tag nrho cov reactivity ntawm imidazoles thiab Benzimidazole yog xa mus los ntawm cov txheej txheem resonance nyob rau hauv uas cov dipolar contributors muaj qhov tseem ceeb kawg. Cov no kwv yees electrophilic nres hauv imidazole ntawm N-3 lossis ib lub nplhaib carbon atom, nucleophilic nres ntawm C-2 lossis C-1 thiab tseem yog qhov amphoteric xwm ntawm cov molecule. Hauv Benzimidazole qhov kev tawm tsam nucleophilic tau kwv yees ntawm C-2. Lub reactivity ntawm Benzimidazole ion ntawm C-2 txoj hauj lwm nrog nucleophiles yog txhim khu kev qha piv nrog rau nruab nrab molecule.
