Abstract
The formation of N-heterocyclic carbenes on a platinum surface is demonstrated. Surface vibrational spectroscopy measurements isolate steps in the transformation from 1,3-diisopropylbenzimidazolium hydrogen carbonate to surface carbene. As the temperature is further increased, the reactive metal transforms the isopropyl groups leading to the effective formation of a new surface carbene.
摘要
在铂表面上形成 N-杂环卡宾得到了证明。表面振动光谱测量分离了 1,3-二异丙基苯并咪唑鎓碳酸氢盐向表面卡宾转化的步骤。随着温度的进一步升高，反应性金属将异丙基转化为新的表面卡宾。
