  日期：——

  Ir(I)-induced tautomerization of a pyridine moiety to a carbene in 2,3-bipyridyls has been successfully achieved where an amide group plays a key role as a hydrogen-bonding acceptor and the carbene tautomer is stabilized by both chelation effect and by hydrogen-bonding.

  成功实现了Ir(I)诱导2,3-联吡啶的吡啶结构转化为卡宾，其中酰胺基团作为氢键接受体发挥了关键作用，卡宾互变异构体则通过螯合效应和氢键的作用得以稳定。
