TL;DR: In this paper, a review of NHC-Ru precatalysts in fundamental organic processes is presented, including hydrogenation, hydrogen transfer, cycloisomerization, cyclopropanation, hydrosilylation, allylation and deallylation, enolester synthesis, heterocycle synthesis, C-C alkyne coupling, Kharasch addition and ATRP.

TL;DR: A new set of ruthenium complexes such as 1 and 2 has been shown to mediate the controlled atom-transfer radical polymerization (ATRP) of vinyl monomers with exceptional efficiency.
Abstract: A new set of ruthenium complexes such as 1 and 2 (the Grubbs ruthenium-carbene complex) has been shown to mediate the controlled atom-transfer radical polymerization (ATRP) of vinyl monomers with exceptional efficiency. Furthermore, there is a striking parallelism between the catalytic activity of these compounds in olefin metathesis and in ATRP.

TL;DR: In this article, the effects of arene and phosphine ligands and of the solvent on polynorbornene and polyoctenamer molecular weight distributions and microstructures were investigated.
Abstract: Highly active catalyst systems for the ring-opening metathesis polymerization (ROMP) of strained (norbornene) and low-strain (cyclooctene) olefins are readily prepared from RuCl2(arene)(PR3) precursors (directly available by addition of a phosphine to the stable [(arene)RuCl2]2 dimers) after activation with (trimethylsilyl)diazomethane. Durene or p-cymene as arene ligands, together with a sterically demanding basic phosphine (typically tricyclohexylphosphine), promoted the formation of the most active polymerization catalysts. The effects of arene and phosphine ligands and of the solvent on polynorbornene and polyoctenamer molecular weight distributions and microstructures were investigated. The excellent functional group compatibility of the catalyst system was illustrated by the synthesis of a variety of polyoctenamers bearing epoxide, acid, ether, ester, acetal, and bromine functionalities. The polymers were isolated in quite good yields. The striking positional influence of the functional group on the...

TL;DR: In this article, five imidazol(in)ium-2-carboxylates bearing cyclohexyl, mesityl, or 2,6-diisopropylphenyl substituents on their nitrogen atoms were prepared from the corresponding N-heterocyclic carbenes by reaction with carbon dioxide.

Abstract: 抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

TL;DR: In this article, a review of recent mechanistic developments in the field of controlled/living radical polymerization (CRP) is presented, with particular emphasis on structure-reactivity correlations and "rules" for catalyst selection in ATRP, for chain transfer agent selection in reversible addition-fragmentation chain transfer (RAFT) polymerization, and for the selection of an appropriate mediating agent in stable free radical polymerisation (SFRP), including organic and transition metal persistent radicals.
