Fanping Huang, Xuejuan Zheng, Xinlei Lin, Linting Ding, Qingde Zhuo, Ting Bin Wen, Hong Zhang, Haiping Xia.Uranium versus Thorium: Synthesis and Reactivity of [ Deqiang Wang, Wanjian Ding, Guohua Hou, Guofu Zi, Marc D.Lanthanides and actinides: Annual survey of their organometallic chemistry covering the year 2019. These solvated species are more stable and less reactive than the unsolvated "naked" anions.Solvation of nucleophilic anions markedly influences their reactivity.Coordination Catalytic Polymerization The initiator is a transition metal complex, and the propagating site of reactivity (*) is a terminal catalytic complex.Anionic Polymerization The initiator is a nucleophile, and the propagating site of reactivity (*) is a carbanion.Cationic Polymerization The initiator is an acid, and the propagating site of reactivity (*) is a carbocation.Radical Polymerization The initiator is a radical, and the propagating site of reactivity (*) is a carbon radical.Many of these addition reactions are known to proceed in a stepwise fashion by way of reactive intermediates, and this is the mechanism followed by most polymerizations.Yifan Dong, Kejian Chang, Xin Xu.Examples of reactivity in the following topics.Extension of the Simmons–Smith reaction to metal-carbynes: efficient synthesis of metallacyclopropenes with σ-aromaticity.
