在这一期的《化学催化》中,Sytniczuk、Kajetanowicz和Grela报道了空间调谐的环状(烷基)(氨基)卡宾(CAAC)配体,以保护可再生脂肪酸甲酯(FAME)乙烯醇分解过程中存在的必要Ru-亚甲基([Ru]= CH 2)中间体。Ru-CAAC络合物令人惊讶的结构特征导致高达740,000的转换数和亚ppm催化剂负载。
In this issue ofChem Catalysis, Sytniczuk, Kajetanowicz, and Grela report on sterically tuned cyclic(alkyl)(amino)carbene (CAAC) ligands to protect the requisite Ru-methylidene ([Ru]=CH2) intermediate present during the ethenolysis of renewable fatty acid methyl esters (FAMEs). Surprising structural characteristics of the Ru-CAAC complexes result in a turnover number of up to 740,000 and sub-ppm catalyst loadings.
