A visible-light-driven photoredox-catalyzed nonaqueous oxidative C-N cleavage of N,N-dibenzylanilines to 2° amides is reported. Further, we have applied this protocol on 2-(dibenzylamino)benzamide to afford quinazolinones with (NH4)2S2O8 as an additive. Mechanistic studies imply that the reaction might undergo in situ generation of α-amino radical to imine by C-N bond cleavage followed by the addition of superoxide ion to form amides.

The development of catalyst based on porous crystalline materials (PCM) constructed from metal ions or clusters and multidentate organic ligands is a topic of great interest. In view of the Lewis acidic and basic properties of PCMs, we report for the first time that MIL-101(Cr) works as a synergistic catalyst for the reduction of imines with trichlorosilane as the hydrogen source. Both ketimines and aldimines were tolerated with this protocol, giving the corresponding amines in moderate to high yields. The operational simplicity as well as mild reaction conditions renders this protocol an attractive approach for the synthesis of amines. Furthermore, a chiral MOF, CMIL-101, was also realized by grafting chiral N-formyl proline derivatives to the open metal sites. Moreover, CMIL-101 exhibited a comparable catalytic performance with its homogeneous counterpart in terms of yields and enantioselectivities.

Learning to cooperate: A straightforward method for the selective N-mono- and dialkylation of amines with alcohols by means of non-metal-based catalysis promoted by TAPC is reported (see scheme). Selectivity of the N-mono- and dialkylation, substrate scope and functional-group tolerance are highlighted with respect to each amine (1° and 2°; aromatic and aliphatic) and alcohol (1°, 2° and 3°; benzylic and aliphatic) component.

Direct N-alkylation of primary amines to secondary/tertiary amines and of secondary amines to tertiary amines has been achieved in excellent yields by employing alkyl, benzylic and allylic halides in the presence of NaHCO 3 in an aqueous medium at an elevated temperature. Amines of different stereoelectronic nature react with ease with different halides. The selective formation of secondary amines and the formation of three different substituted tertiary amines are some of the interesting features of this methodology. Reaction in an aqueous medium, operationally convenient conditions, excellent yields and innocuous byproducts, and the absence of transition-metal catalysts, expensive bases, solid supports and the formation of undesired quaternary ammonium salts makes this method a green chemical process.
