Transition metal catalyzed asymmetric allylic alkylation (AAA) reactions represent a versatile and powerful tool for enantioselective C-C bond formation.
A novel azopyridine-based Ru(Ⅱ) complex [Ru(bpy)2(L1)2]2+ (bpy =2,2-bipyridine, L1 =4,4-azopyridine) was designed and synthesized as a potential glutathione (GSH)-responsive photoactivated chemotherap
Ring-opening metathesis polymerization (ROMP) is a powerful toolkit for the preparation of random, block and alternating functionalized copolymers.
Developing an efficient, atom-and step-economic approach for C-C bond formation is always an important concern for synthetic chemistry.
Since the pioneering work of J.-M.Lehn,1 supramolecular polymers (SPs) have drawn considerable attention because of their important applications in materials science.
Stimuli-responsive materials have recently attracted widespread interest in materials science and technology for their conspicuous performance in many aspects.
Inspired by the discovery of graphene, in the recent years two-dimensional (2D) materials have become one of the most attractive subjects in materials science.
A hexaazatriphenylene (HAT) derivative (compound 1) that bears four n-dodecyl chains and two thienyl groups was designed and synthesized.Further light induced oxidation coupling of the adjacent thioph
甲基化反应在生物活性分子修饰中发挥重要作用,相对于传统的碘甲烷或重氮甲烷,甲醇作为一种丰富、廉价、绿色、可再生的甲基化试剂受到广泛关注.近年来以醇为原料的酮α-烷基化反应取得很大进展,这些反应中底物多为苯基醇或长链脂肪醇,而以短链醇(如甲醇)为底物的研究十分稀少.最近,Donohoe等成功实现了以甲醇为原料的酮α-甲基化反应(Scheme 1),反应以Rh作为催化剂,条件温和,产率高.
过渡金属催化的不饱和键双官能化在有机合成中具备广泛的应用.作为具有路易斯酸性的后过渡金属,金催化剂能够有效的实现不饱和键的双官能化.通常情况下,是通过采用强氧化剂产生Au(Ⅲ)/Au(Ⅰ)循环,或者通过与钯催化剂组成双金属体系实现此类反应.然而这两种方法分别需要当量的强氧化剂和当量的金催化剂.相比之下,通过将光催化引入金催化体系组成光-金双催化体系,1-2既可以避免上述两种当量试剂的使用,又能够高
