Oxidative Kinetic Resolution of Acyclic Amines Based on Equilibrium Control
Akiyama, Takahiko,Ito, Yui,Miyashita, Hiromitsu,Saito, Kodai,Yamanaka, Masahiro
supporting information, (2020/04/10)
An oxidative kinetic resolution of racemic acyclic amines was developed using an imine derivative as the resolving reagent and chiral phosphoric acid as the catalyst to give enantiomers in good yields with high to excellent enantioselectivities. The key t

Despite the wide applicability of enantioselective Br?nsted acid catalysis, experimental insight into transition states is very rare, and most of the mechanistic knowledge is gained by theoretical calculations. Here, we present an alternative approach (de
Room temperature hydroamination of alkynes with anilines catalyzed by anti-Bredt di(amino)carbene gold(i) complexes
Hu, Xingbang,Martin, David,Bertrand, Guy
, p. 5993 - 5996 (2016/07/16)
The room temperature hydroamination of alkynes with phenylhydrazine and anilines was achieved with an anti-Bredt di(amino) carbene gold(i) chloride as precatalyst, in the presence of KBArF as chloride scavenger. These reactions were highly regioselective and excellent conversions were obtained (up to 99%) for a series of alkynes and anilines.
Comparison of the 13C (C=N) chemical shifts of substituted N-(phenyl-ethylene)-anilines and substituted N-(benzylidene)-anilines

Comparison of 13C NMR of C=N bond chemical shifts δC(C=N) in substituted N-(phenyl-ethylene)-anilines XArC(Me)=NArY (XPEAYs) with that in substituted N-(benzylidene)-anilines XArCH=NArY (XBAYs) was carried out. The δC(C=N)

Mildly does it: A highly enantioselective catalyst for the hydrogenation of N-aryl imines is described (see scheme). This catalyst offers practical advantages because it operates under very mild conditions and is based on an Ru complex with a diamine as t
Rhodium(III)-catalyzed hydroamination of aromatic terminal alkynes with anilines
Kumaran, Elumalai,Leong, Weng Kee
experimental part, p. 1068 - 1072 (2012/04/04)
The dinuclear Rh(III) species [Cp*RhCl2]2 catalyzes the hydroamination reaction between an aromatic terminal alkyne (ArCCH) and an aniline (Ar′NH2), in the presence of a salt additive, to afford the ketimine Ar′N=C(Me)(Ar). A reaction pathway has been proposed on the basis of experimental and computational studies.

supporting information; experimental part, p. 4183 - 4185 (2011/06/25)
A novel reaction, the potassium hydride mediated synthesis of fulvenes, is described. The synthesis utilizes N-aryl imines as an inexpensive starting material affording novel substituted aminofulvenes. It is proposed that the presence of the metalated enamine as well as the imine (ratio 21) leads to the formation of an initial dimerization and a transient trimerization product, which cyclizes, giving rise to the aminofulvene.
Novel amido-complexes for the efficient asymmetric hydrogenation of imines
