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.
