second generation Hoveyda–Grubbs catalysts: 1,3-dimesityl-acenaphthylenyl-4,5-imidazolin-2-ylidene (BIAN-NHC) ruthenium isopropoxybenzylidene dichloride 3 and 1,3-bis(2,6-dimethylphenyl)-2,3-dihydro-1H-imidazole Cl2Ru(CH-o-O-i-PrC6H4) 4. The electrochemical and catalytic behavior of these new complexes was compared with the conventional NHC carbene Hoveyda II IMes-type complexes 1 and 2 for ring closing
此手稿描述的合成和新的第二代格拉布催化剂结构研究:1,3-二基苊基-4,5-咪唑啉-2-亚基(卞-NHC)钌isopropoxybenzylidene二氯化3和1,3-双(二2,6-二甲基苯基)-2,3-二氢-1- ħ咪唑氯2的Ru(CH- ö -Oi-PRC 6 ħ 4)4。这些新的配合物的电化学和催化行为与常规NHC卡宾的Hoveyda II IMES型复合物进行比较1和2用于闭环复分解反应。
