A chlorination method for the selective substitution of well-defined isolated silanol groups of the silica surface has been developed using the catalytic Appel reaction. Spectroscopic analysis, complemented by elemental microanalysis studies, reveals that a quantitative chlorination could be achieved with highly dehydroxylated silica materials that exclusively possess non-hydrogen bonded silanol groups. The employed method did not leave any carbon or phosphorus residue on the silica surface and can be regarded as a promising tool for the future functionalization of metal oxide surfaces.
已开发出一种使用催化阿佩尔反应对二氧化硅表面明确分离的硅醇基团进行选择性取代的氯化方法。光谱分析辅以元素微量分析研究表明，对于仅具有非氢键合硅醇基团的高度脱羟基二氧化硅材料，可以实现定量氯化。所采用的方法不会在二氧化硅表面留下任何碳或磷残留物，可被视为未来金属氧化物表面功能化的一种有前景的工具。
