我们在此报道了碱促进从相应的吡啶鎓盐生成空间位阻1,3,5-三芳基2-吡啶基。由此产生的2-吡啶基被S-8和Me2SAuCl捕获，分别形成2-吡啶硫酮和2-吡啶基-金(I)络合物。亚吡啶重排为吡啶并[1,2-a]吲哚表明2-亚吡啶的卡宾中心具有高反应性。
We herein report a base-promoted generation of sterically hindered 1,3,5-triaryl 2-pyridylidene from the corresponding pyridinium salt. The thus-generated 2-pyridylidene was trapped by S-8 and Me2SAuCl to form 2-pyridinethione and a 2-pyridylidene-gold(I) complex, respectively. Rearrangement of pyridylidene to pyrido[1,2-a]indole indicates high reactivity of the carbene center of 2-pyridylidene.
