Pyrrole reacts with [Os3(CO)12] in refluxing decalin to give [Os3H2(CO)9(µ3-C4H2NH)](yield 54%) which is analogous to the benzene derivative [Os3H2(CO)9(µ3-C6H4)] and is not related to known pyrrolyl complexes such as [Fe(η5-C5H5)(η5-C4H4N)] in which the pyrrolyl is deprotonated at nitrogen. N-Methylpyrrole forms a directly related compound differing, however, in its much faster exchange of the hydrido-ligands
吡咯在回流萘烷中与[Os 3(CO)12 ]反应生成[Os 3 H 2(CO)9(µ 3 -C 4 H 2 NH)](产率54%),与苯衍生物[Os]类似3 ħ 2(CO)9(μ 3 -C 6 ħ 4)〕和不相关的公知的吡咯基配合物如[铁(η 5 -C 5 H ^ 5)(η 5 -C 4 H ^ 4 N)]中吡咯基在氮气中被去质子化。ñ-甲基吡咯形成直接相关的化合物,但是其氢化物-配体的交换快得多。
