2-substituted benzimidazoles and imidazoles have been synthesized from long-chain alkenoic acids. The reactions occurred under relatively mild conditions and afforded the desired product in good yields. The structures of these compounds have been elucidated by elemental and spectral (IR, 1H NMR, 13C NMR, mass) analyses. Furthermore, compounds were screened for in vitro antibacterialactivity against the
从长链烯酸合成了一系列新颖的2-取代的苯并咪唑和咪唑。反应在相对温和的条件下进行,并以高收率得到所需产物。这些化合物的结构已通过元素分析和光谱分析(IR,1 H NMR,13 C NMR,质量)进行了阐明。此外,针对两种革兰氏阳性和两种革兰氏阴性细菌的代表性组筛选化合物的体外抗菌活性。还测试了所有合成的化合物对五种真菌菌株的抑制作用。各种化合物显示出对测试生物的有效抑制作用。

partner were found to affect the opticalproperties in CHCl3 solution as a result of steric and electronic factors. The spectroscopic measurements in film revealed that the bulky trisiloxane group helps π-conjugated polymers to form the π-stacked structure upon thermal annealing. The proton doping experiment was also carried out to find out that the protonation of imidazole nitrogen results in the different
