Abstract

Palladium nanoparticles are dispersed and stabilized in organically modified silicate (Pd@MTES), and characterized by a number of spectroscopic techniques, including FTIR, TEM, SEM, and XPS. The catalytic effect of this material toward the hydrosilylation of aldehydes and ketones is explored, and the scope of the reaction investigated, with 26 examples provided. This reaction proceeds under neat conditions via heterogenous catalysis, and a mechanistic pathway supported by DFT calculations is proposed.

纳米分散并稳定在有机改性硅酸盐中的钯作为一种异源催化剂,用于在纯净条件下将醛转化为 O-硅醚衍生物。
钯纳米粒子在有机改性硅酸盐(Pd@MTES)中分散和稳定,并通过傅立叶变换红外光谱、TEM、SEM 和 XPS 等光谱技术进行表征。研究人员探讨了这种材料对醛和酮的氢硅化反应的催化作用,并提供了 26 个实例,对反应的范围进行了研究。该反应在纯净条件下通过异源催化作用进行,并提出了一条由 DFT 计算支持的机理途径。
