A highly efficacious photoinduced reversible complexation-mediated polymerization (photo-RCMP) system using amino alcohol N-oxide as the catalyst has been developed, allowing access to controlled high-molecular-weight polymers of different methacrylates (Mn = 497–815 kg/mol, Đ < 1.5), which is very challenging for those known catalyti...

A facile method for the construction of the aspidosperma core from indole functionalized with a nonterminal N -allenamides and dimethyl methylenemalonate is described. Various polysubstituted tetracyclic spiroindolines (27 examples) were afforded in good yields (61-90%) with >99:1 dr and >99:1 Z/E selectivity under mild conditions.

In this review, we summarize in detail the research on RCMP in the last ten years since its birth, mainly focusing on the development and evolution of catalytic systems, photo-induced RCMP and the special applications derived from their inherent characteristics.

在聚烯烃行业蓬勃发展的几十年中,如何合成具有独特结构和功能的聚烯烃一直是高分子化学家不断追求的目标。时至今日,科学家们已经可以通过调控单体结构、催化剂中心金属、配体结构以及聚合条件等来合成丰富多彩的聚烯烃。在这品类繁多的聚烯烃中,主链上含有脂肪环的聚烯烃因具有良好的热稳定性和透明度受到了广泛的关注。α,ω-双烯烃的配位聚合是获得主链含脂肪环的聚...

Highly branched polymers are very promising and suitable for a variety of applications. Herein, a series of oil-soluble and branched polymethacrylates are synthesized efficiently via atom transfer radical copolymerization of 2-ethylhexyl methacrylate (EHMA) with different divinyl branchers. More remarkably, for the first time, it is found...
