Reductive dimerization and reduction of imines using lanthanum metal
Nishino, Toshiki,Nishiyama, Yutaka,Sonoda, Noboru
, p. 131 - 135 (2007/10/03)
The treatment of N-benzylideneaniline (1a) with a half-equivalent of lanthanum metal and a catalytic amount of iodine gave the reductive dimerization product of 1a, a vic-diamine, in good yield. Various vic-diamines were synthesized from aldimines in this
A novel reductive dimerization/oxidative dehydrogenation of aldimines mediated by lanthanoid metals

, p. 514 - 520 (2007/10/03)
A lanthanoid metal-mediated novel reductive dimerization/oxidative dehydrogenation of a variety of aldimines has been achieved. Aromatic aldimines (1) were dimerized in the presence of 0.5 mol of ytterbium metal (Yb) and 1-naphthaldehyde (1-NpCHO) to give
Indium-mediated deoxygenation of nitrones, N-oxides and deoxygenative reductive coupling of nitrones to vicinal diamines
Jeevanandam, Arumugasamy,Cartwright, Charles,Ling, Yong-Chien
, p. 3153 - 3160 (2007/10/03)
We reported transformation of nitrones selectively either to aldamines or vicinal diamines and deoxygenation of N-oxides using Indium at ambient temperature in good yields.
Samarium diiodide/nickel diiodide an efficient system for homo and heterocoupling reactions of imines
Machrouhi, Fouzia,Namy, Jean-Louis
, p. 1315 - 1318 (2007/10/03)
Samarium diiodide in the presence of a catalytic amount of nickel diiodide mediates a very fast dimerization of imines into vicinal diamines and the mixed coupling of imines and ketones to give β-amino alcohols.
Reductive coupling of aldimines mediated with samarium catalyzed by Cp2TiCl2
Liao, Puhong,Huang, You,Zhang, Yongmin
, p. 1483 - 1486 (2007/10/03)
Reductive coupling of aldimines into vicinal diamines mediated with samarium catalyzed by Cp2TiCl2 proceeds in refluxing THF with good yields.
Novel reductive coupling of aldimines to vicinal diamines
Baruah, Bipul
, p. 6747 - 6750 (2007/10/02)
Reductive coupling of aldimines into vicinal diamines has been performed by the action of aluminium/bismuth powder and potassium hydroxide in methanol at ambient temperature in high yields.
Electrosynthesis of N-Substituted DL-Arylglycineesters and 1,2-Diarylamino-1,2-diarylethanes by Cathodic Reduction of Azomethines in the Presence of Carbon Dioxide
Hess, U.,Thiele, R.
, p. 385 - 399 (2007/10/02)
The electroreduction of the N-arylidene-arylamines 1-12 in CO2-saturated solvents of low proton availability as DMF at markedly more positive potentials than carbon dioxide end up in carboxylating the C-atom and hydrogenating the nitrogen of the C=N-double bond.The resulting N-arylsubstituted DL-arylglycines and traces of carbamates may be isolated as esters, adding ethylchloride during the electrolysis.A competing pathway of the electrocarboxylation is the C-C-hydrodimerisation and the hydrogenation of the C=N-double bond, whose importance increases with the water content of the solvent.Based on cyclic-voltametric evidence and product analysis the mechanism of the reductive electrocarboxylation reaction is discussed in terms of nucleophilic attack of the azomethine anion radical on a proton or CO2.
