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.

通过单点置换法对二氧化硅表面进行清洁氯化†

使用催化Appel反应，已经开发出一种氯化方法，用于选择性取代二氧化硅表面上明确定义的分离的硅烷醇基团。光谱分析和元素微分析研究相辅相成，结果表明，使用完全具有非氢键结合的硅烷醇基团的高度脱羟基的二氧化硅材料，可以实现定量氯化。所采用的方法在二氧化硅表面上没有留下任何碳或磷的残留物，可以被认为是将来金属氧化物表面功能化的有前途的工具。
