金催化下亚乙烯基环丙烷有两种截然不同的反应途径,分别是经过形成卡宾的中间体和不形成卡宾直接接受亲核进攻两个过程.在通过对以往关于金卡宾文献的查阅和研究,这是基于亚乙烯基环丙烷的两性性质而产生的一种形成金卡宾的新方式1,2.
Carbon-carbon bonds are the fundamental element in the organic chemistry.The selective C-C bonds cleavage has been considered as an attractive research in organic chemistry owing to its high efficienc
As a new kind of green material,isotactic polylactide(PLA) derived from rac-lactide(rac-LA) is receiving much attention due to its superior physical and mechanical properties.
Fluorine-containing compounds have drawn much attention due to their unique physicochemical and biological properties.
The [FeFe]-and [NiFe]-H2ases have been shown to catalyze the interconversion of dihydrogen with protons and electrons at high rates.Although hydrogenases have been utilized in fuel cells,their practic
The sustainable generation of the energy vector H2 would provide a possible solution to a fossil-free economy,and the improvement of H2 evolution catalysts is therefore attracting much current attenti
Recently H2-evolution reactions(HER) have attracted considerable attention.[1] We have found that complexes NHC+-CS[Fe2(CO)6]-,(μ-RS)Fe2(CO)6(μ-R′NHCS) and(μ-Ph2P)Fe2(CO)6(μ-OH) can catalyze dihydroge
During the past two decades amidinate ligands were successfully employed in organometallic chemistry of rare-earth metals,that allowed for the synthesis and isolation of new series of highly reactive
Metal-catalyzed cross-couplings provide powerful,concise,and accurate methods to construct carbon-carbon bonds from organohalides and organometallic reagents.
芳甲基硫醚和芳甲基砜类化合物在药物化学和农药化学中是一类重要的物质[1],另外芳甲基硫醚类化合物可作为交叉偶联反应中常用底物[2].传统合成芳甲基硫醚化合物有三种方法,一是亚砜的还原[3],二是芳基硫酚直接与碘甲烷等甲基化试剂反应[4],三是芳烃的C-H 活化与二甲基二硫醚反应[5].
