介绍了亲核Fe络合物Bu 4 N [Fe（CO）3（NO）]（TBA[Fe]）催化的卡宾转移到极性X-H-键的反应的深入研究。而醇是不反应的，硫醇和仲胺是反应性的，硅烷显示适度的活动。Hammett关联表明存在X-H-酸度依赖的二分法。
An in‐depth study of carbene transfer reactions into polar X−H‐bonds catalyzed by the nucleophilic Fe‐complex Bu4N[Fe(CO)3(NO)] (TBA[Fe]) is presented. Whereas alcohols are unreactive, thiols and secondary amines are reactive, silanes showed modest activities. Hammett correlations indicate the presence of an X−H‐acidity dependent mechanistic dichotomy.
