In this work, the preparation, characterization and investigation of catalytic activity ruthenium hydride catalyst, [RuHCl(CO)(PPh3)3], supported on MWCNT in the synthesis of β,γ-unsaturated ketones via carbon–carbon bond formation are reported. In the first reaction step, the MWCNTs were modified with 1,2-ethanedithiol, and in a second reaction step, the catalyst was attached to MWCNTs via this linker
在这项工作中,报道了负载在MWCNT上的钌氢化物催化剂[RuHCl(CO)(PPh 3)3 ]的制备,表征和研究,该反应通过碳-碳键形成合成β,γ-不饱和酮。在第一反应步骤中,将MWCNT用1,2-乙二硫醇改性,并且在第二反应步骤中,催化剂经由该接头连接至MWCNT 。该催化剂的特点是采用漫反射紫外可见光谱和FT-IR光谱技术,SEM,ICP和元素分析方法。催化剂可重复使用几次,而不会明显降低其催化活性。
