摘要报道了N-杂环卡宾(NHC)的银配合物的合成,结构和抗菌研究。所有的银-NHC络合物(1a-f)是由苯并咪唑鎓盐与Ag 2 O在二氯甲烷中作为溶剂在室温下反应制得的。这些新化合物的特征在于1 H NMR,13 C NMR,IR和元素分析技术,可支持所提出的结构。通过单晶X射线衍射对氯[1-(2,4,6-三甲基苄基)-3-(甲氧基乙基)苯并咪唑-2-亚烷基]银(I)配合物进行结构表征。针对一系列革兰氏阳性和革兰氏阴性细菌的体外抗菌活性以及对白色念珠菌和热带念珠菌的抗真菌活性,筛选了一系列新的Ag–NHC复合物。
Synthesis of rhodium complexes derived from benzimidazolin-2-ylidene ligands and first used for the addition of arylboron to benzonitriles
摘要:
Benzimidazolium salts and their new rhodium complexes ([RH(COD)(NHC)Cl]) were synthesized and characterized by elemental analysis, H-1 NMR, C-13 NMR, and IR spectroscopy. The addition of arylboron to benzonitriles in the presence of a catalytic amount of rhodium NHC complexes was examined. Corresponding carbonyl compounds were obtained in good yields. This method allows for the preparation of a wide variety of carbonyl compounds in moderate to excellent yields and displays a high level of activity for the addition of arylboron to nitriles.
