Highly Efficient Etherification of Silanes by Using a Gold Nanoparticle Catalyst: Remarkable Effect of O_2

摘要

In conclusion, we successfully developed Au/HAP_(nano) for the highly efficient etherification of silanes with alcohols in the presence of O_2. Various silyl ethers could be obtained from diverse combinations of silanes with alcohols. Furthermore, the Au/HAP_(nano) catalyst was reusable with high efficiency. This remarkable catalytic performance was elicited by O_2. This O_2 effect on AuNPs leads to the unique phenomenon of higher catalytic activity of Au/HAP_(nano) at lower temperature in the etherification of bulky silanes.
