The first Pd-based heterogeneous homo- and cross-coupling reactions for the fluorenones synthesis are reported. The palladium supported SBA-functionalizd 1,2-dicarboxylic acid ([email protected]) was prepared and characterized by the FT-IR, TGA, AAS, TEM, and EDS measurements. The prepared catalyst exhibited a high performance in some homo and cross coupling reactions for the synthesis of fluorenone derivatives using 2-bromo or 2,7-dibromo fluorenone in ethanol-water as green solvent medium.

钯负载的SBA-官能化的1,2-二羧酸：第一次基于Pd的芴酮异质合成

首次报道了芴酮合成的基于钯的异质均相和交叉偶联反应。制备了钯负载的SBA-官能化的1,2-二羧酸（[受电子邮件保护]），并通过FT-IR，TGA，AAS，TEM和EDS测量对其进行了表征。所制备的催化剂在乙醇-水为绿色溶剂介质中使用2-溴或2,7-二溴芴酮合成芴酮衍生物时，在某些均相和交叉偶联反应中表现出较高的性能。
