The complex [TpMe2Ir(C6H5)2(N2)] reacts with several 2‐substituted pyridines to generate N‐heterocyclic carbenes resulting from a formal 1,2‐hydrogen shift from C6 to N. In this paper we provide a detailed report of the scope and the mechanistic aspects (both experimental and theoretical) of the tautomerisation of 2‐substituted pyridines.
配合物[Tp Me2 Ir(C 6 H 5)2(N 2)]与数个2-取代的吡啶反应,生成从C 6到N的正式1,2-氢转移而生成的N-杂环卡宾。我们提供了2取代吡啶互变异构作用的范围和机理(实验和理论方面)的详细报告。
