The nucleophilic iron complex Bu4N[Fe(CO)3(NO)] (TBA[Fe]) catalyzes the direct intramolecular amination of unactivated C(sp3)−H bonds in alkylaryl azides, which results in the formation of substituted indoline and tetrahydroquinoline derivatives.

Investigations on Aromatic Amino-Claisen Rearrangements
rings: Treatment of N‐arylallylamine with an aryl or alkenylhalide under palladium catalysis (see scheme; dba=dibenzylideneacetone, SPhos=2‐dicyclohexylphosphanyl‐2′,6′‐dimethoxybiphenyl) resulted in intramolecular cyclization to form the arylmethyl‐substituted aziridine with concomitant CC bond formation. The experiments for the elucidation of the reaction mechanism are also described.

The rhodium-catalyzed regioselective amination of tertiary allylic trichloroacetimidates with unactivated aromatic amines is a direct and efficient approach to the preparation of α,α-disubstituted allylic aryl amines in good yield and with excellent regioselectivity. This method is applicable to a variety of unactivated primary and secondary amines and allows for the preparation of reverse prenylated

A novel and efficientapproach to allyloxyamines by the allylation of nitrosoarenes with α‐chiralallylboronates is described. CO bond formation occurs with high stereospecificity and the product allyloxyamines are easily transformed into valuable chiral building blocks such as isoxazolidines and allylic alcohols. The reaction features complete regioselectivity (O‐selectivity), high E/Z selectivity
