Radical cations of 1,2-bis(dialkylamino)benzenes: Restricted rotation about the C-NMe2 bond

The 1,2-bis(dialkylamino)benzene radical cations 2a-c.+ were generated by oxidation of the parent compounds with iodine or lead tetraacetate. ESR and ENDOR studies of 2a.+ and 2b.+ gave evidence of a restricted rotation about the C-NMe2 bond; based on the results of 2c.+ the different N-methyl proton splittings in 2a++ and 2b.+ were assigned to the exo and endo N-methyl groups.

Well-Defined Phosphine-Free Iron-Catalyzed N-Ethylation and N-Methylation of Amines with Ethanol and Methanol

An iron(0) complex bearing a cyclopentadienone ligand catalyzed N-methylation and N-ethylation of aryl and aliphatic amines with methanol or ethanol in mild and basic conditions through a hydrogen autotransfer borrowing process is reported. A broad range of aromatic and aliphatic amines underwent mono- or dimethylation in high yields. DFT calculations suggest molecular hydrogen acts not only as a reducing agent but also as an additive to displace thermodynamic equilibria.
