  Methyl substituted 2-phenyldiazenyl-N-vinylpyrroles when refluxed in toluene in the airflow are unexpectedly oxidized at their methyl substituents retaining the pyrrole and N-vinyl moieties intact. The major products of the autooxidation are hydroxyalkyl derivatives (yield up to 60%), the corresponding aldehydes being formed in minor quantities (yield up to 21%). This non- typical oxidation of substituted

  甲基取代的 2-苯基二氮烯基-N-乙烯基吡咯在甲苯中在气流中回流时出乎意料地在其甲基取代基处被氧化，保持吡咯和 N-乙烯基部分完整。自动氧化的主要产物是羟烷基衍生物（产率高达 60%），相应的醛以少量形成（产率高达 21%）。取代吡咯的这种非典型氧化为苯基二氮烯基吡咯染料的官能化开辟了一种概念上的新方法。

  N-Vinylpyrroles and -indoles bearing electron-withdrawing substituents at the pyrrole ring are mercurated, with 1 equivalent of Hg(OAc)2 in dry MeCN (20–80 °C), regioselectively at the vinyl group (yields are almost quantitative), while their congeners without electron-withdrawing functions are mercurated both at the N-vinyl group and the pyrrole ring.
