Herein, we report an efficient electrochemical method for the synthesis of N-alkylated sulfoximines by electrochemical oxidative C(sp3)-H/N-H coupling of sulfoximines and diarylmethanes. In addition, we used the same conditions for electrochemical dehydrogenative amination of diarylmethanes with benzophenone imine as an aminating agent. The reactions showed good functional group tolerance and afforded the corresponding products in moderate to good yields without the use of a stoichiometric oxidant, a metal catalyst, or an activating agent.

Catalytic conditions for the α-arylation of aryl nitromethanes have been discovered using parallel microscale experimentation, despite two prior reports of the lack of reactivity of these aryl nitromethane precursors. The method efficiently provides a variety of substituted, isolable diaryl nitromethanes. In addition, it is possible to sequentially append two different aryl groups to nitromethane. Mild oxidation conditions were identified to afford the corresponding benzophenones via the Nef reaction, and reduction conditions were optimized to afford several diaryl methylamines.

An enantioselective C-H iodination reaction using a mono-N-benzoyl- protected amino acid has been developed for the synthesis of chiral diarylmethylamines. The reaction uses iodine as the sole oxidant and proceeds at ambient temperature and under air.

Cu(OAc)2-mediated coupling of benzophenone N,N,N- trimethylhydrazonium salts and aryl boronic acids proceeded to afford N-aryl imines.
Mapping the active site in a chemzyme: Diversity in the N-substituent in the catalytic asymmetric aziridination of imines
Zhang, Yu,Lu, Zhenjie,Desai, Aman,Wulff, William D.
supporting information; experimental part, p. 5429 - 5432 (2009/06/20)
(Chemical Equation Presented) The active site of the aziridination catalyst derived from either the VANOL or VAPOL ligand and B(OPh)3 is larger than expected and can accommodate not only significant substitution on the diarylmethyl unit of the imine but also that alkyl (but not perfluorylalkyl) substituents on the aryl groups lead to enhanced rates and enantioselection. The screen of diarylmethyl N-substituents on the imine revealed that the 3,5-di-tert-butyldianisylmethyl group (BUDAM) gave exceptionally high asymmetric inductions for imines of aryl aldehydes.
Orthoamides, LXIV [1]. Formylation of aromatic compounds by tris(dichloromethyl)amine and oligoformylamine derivatives in the presence of superacids

Tris(dichloromethyl)amine (4), triformamide (1) and tris(diformylamino) methane ( formyl-aalen ) (2) can be activated by addition of trifluoromethanesulfonic acid. The formylating systems thus formed transform activated aromatic compounds, such as toluene, anisole or 2,4-dimethoxybenzene to the corresponding aldehydes. The formylating ability of systems from 4 and superacids, such as FSO3H, FSO3H/SbF5, C 4F9SO3H, and mixtures of aluminum chloride with C4F9SO3H and chlorosulfonic acid, respectively, is compared. In general, low reaction temperatures (-20 to -10°C) are necessary to obtain aldehydes with acceptable to good yields. Remarkably, at higher temperatures (~ 100°C) compound 4 can also act as a formylating agent in the presence of suitable zeolites, as e. g. zeolite HBEA. Reaction mechanisms of the new formylation reactions are proposed.
Synthesis of substituted benzhydrylamines

, p. 113 - 115 (2007/10/03)
The synthesis of para di- and monosubstituted benzhydrylamines by addition of Grignard reagents to benzonitriles and subsequent reduction, is evaluated and discussed. The reduction step with sodium borohydride allows simple handling and mild conditions. An optimized synthesis of 4,4'-dimethoxybenzhydrylamine by this method is disclosed.
