A new strategy to access linear amines from terminal olefin precursors is reported. This two-step, one-pot hydroamination methodology employs sequential oxidation and reduction catalyticcycles. The formal hydroamination transformation proceeds with excellent regioselectivity, and only the anti-Markovnikov product is observed. Up to 70% yield can be obtained from styrenes or aliphatic olefins and either

without any directing group by cross-dehydrogenative coupling between unactivatedC(sp3)–H and C(sp3)–Hbonds has been established for the first time, which provides a good complement to C(sp3)–Hactivation reactions and expands the field of Fe-catalyzed C–H functionalizations. Many different C(sp3)–Hbonds in cyclic alkanes, cyclic ethers, and toluene derivatives can be used as coupling partners. Mechanistic
A new catalytic amination of aromatic olefins with anilines is presented. In a domino reaction, substituted quinoline derivatives are obtained in the presence of cationic rhodium complexes, such as [Rh(cod)2]BF4, and PPh3. Ethylbenzene is formed as a by-product in this new oxidative reaction. The first transition metal catalyzed anti-Markovnikov hydroamination of styrene with anilines occurs as a side

or azo compounds. Herein, we report an acid mediated annulation reaction of aliphatic amines and nitrosoarenes to provide indole derivatives. The elusive directannulation of aliphatic amines and nitrosoarenes via simultaneous C-C and C-N bond formation was achieved under metal free conditions. This conceptually novel method for indolesynthesis does not require pre-functionalization steps for the

demonstrated that Pt10 activatesamine to be electrophilic while Pt1δ+ activates C=C by π-bonding to make β-C nucle-ophilic. The attack of nucleophilic β-C to electrophilic amine affords the anti-Markovnikov addition. This strategy proves highly effective to a variety of substrates in anti-Markovnikov C-N formation, including aromatic/aliphatic amines react-ing with aromatic olefins, aromatic/aliphatic olefins
