The thermal reactions of the closed-shell, "naked" gold-carbene complex Au(CH2) with methane have been explored by using FTICR mass spectrometry complemented by quantum chemical (QC) calculations at the CCSD(T)//BMK level of theory. Mechanistic aspects for this unprecedentedly efficient carbene insertion in the C-H bond of methane have been addressed and the origin of the counterintuitive high reactivity of Au(CH2) towards this most inert hydrocarbon is discussed.
采用傅立叶变换离子回旋共振质谱（FTICR-MS）联用技术，并结合 CCSD(T)//BMK 理论水平的量子化学（QC）计算，对“裸”金卡宾配合物[Au(CH2)]+与甲烷的封闭壳层热反应进行了研究。本文探讨了甲烷 C-H 键中前所未有的高效卡宾插入反应的反应机理，并讨论了[Au(CH2)]+与这种最惰性的碳氢化合物具有反常高反应性的起源。
