NHC–Ag complex derived from N -(1-naphthalenylmethyl)-substituted benzimidazolium salt L12 , affording the corresponding alcohol in 92% yield and with 92% ee. Moreover, the evaluation of an Ir catalyst precursor showed that cationic [Ir(cod) 2 ]BF 4 complex could be used. Furthermore, the introduction of a chiral hydroxyamide side arm into the benzimidazolium salt was critical for the successful design of
A series of cholesterol-appended benzimidazoliumsalts 1–9 have been designed and synthesized. They have been explored in gel chemistry. The gelation of the benzimidazoliumsalts is dependent on the nature of the counteranions. In addition, the gelation behavior of the gelators is linked with the presence of both π-stacking and cholesteryl motifs. Whereas bisbenzimidazolium salt 2 forms a gel in d
已经设计并合成了一系列胆固醇附加的苯并咪唑鎓盐1–9。他们已经在凝胶化学中进行了探索。苯并咪唑盐的凝胶化取决于抗衡阴离子的性质。另外,胶凝剂的胶凝行为与π-堆积和胆固醇基序的存在有关。而bisbenzimidazolium盐2所形成的凝胶在二甲亚砜/ H 2 O(1:1,V / V)本身,在类似条件下,monobenzimidazolium盐4和6表现出凝胶化在F的存在-离子和验证F的视觉传感-。作为应用,凝胶相为2有效去除废水中的有毒染料。此外,所有凝胶均在较宽的电压范围内显示出热活化的半导体特性。

investigation of the reaction progress as a function of time revealed that an iridium species, which was generated after 5 h of reaction time, catalyzed the stereoselective reduction with almost perfect facial selection of the ketone. An attempt to obtain a catalytic active species from the reaction of [Ir(cod)2]BF4 and chiral azolium salt has been made. The newly obtained iridium species promoted the

An aptamer-N-heterocyclic-carbene metal complex conjugate (aptamer-NHCM conjugate) or an aptamer-bis-N-heterocyclic-carbene metal complex conjugate (aptamer-bis-NHCM conjugate) includes an aptamer coupled through a hydrolytically stable bond to an N-heterocyclic-carbene metal complex (NHCM) or a bis-N-heterocyclic-carbene metal complex (bis-NHCM). The aptamer-NHCM conjugate is prepared where the chosen aptamer displays selective binding to a cell specific receptor, such that the cytotoxic NHCM can be directed specifically to cells responsible for a target disease (e.g., a specific cancer type). A method of preparing the aptamer-N-heterocyclic-carbene metal complex conjugate involves installing a coupling group to an N-heterocyclic-carbene metal complex that can specifically bond with a functional group on an aptamer; the bond, covalent or non-covalent, is stable hydrolytically in the absence of an environment that promotes intentional cleavage of the bond.
