for designing chemically and biologically useful organosilicon compounds. Heterogeneous catalytic systems sufficiently active, selective, and durable for dehydrosilylation reactions under mild conditions have been lacking to date. Herein, we report that the hydrophobic characteristics of the underlying supports can be advantageously utilized to enhance the efficiency of palladium nanoparticles (Pd NPs)
Si-H键的直接偶联已成为设计化学和生物学上有用的有机硅化合物的一种有前途的策略。迄今为止,缺乏在温和条件下对于脱氢硅烷化反应具有足够活性,选择性和耐用性的非均相催化体系。在本文中,我们报道了基础载体的疏水特性可以有利地用于增强钯纳米颗粒(Pd NPs)的有机硅烷脱氢偶联效率。通过这种出色的表面润湿性控制,与现有催化剂相比,改性催化剂对有机硅烷与水,醇或胺的脱氢缩合反应表现出明显更高的效率和耐用性。在更广泛的范围内,
