Amino-alcohol cyclization: Selective synthesis of lactams and cyclic amines from amino-alcohols
Pingen, Dennis,Vogt, Dieter
, p. 47 - 52 (2014/01/06)
By employing an amination catalyst, previously used in the direct synthesis of amines from alcohol with ammonia, n-amino-alcohols could be selectively cyclized to either the amide or the amine. By the addition of water, the amine could be produced as the major product whereas adding a sacrificial ketone as a hydrogen acceptor resulted in the amide as the major product. Without an additive a mixture of both the amine and the amide was observed. N-substituted amino-alcohols solely gave cyclic amines under these conditions. From 2-(n-alkanol) anilines the cyclic amines were produced, where the n-propanol derivative selectively formed quinoline as the major product.

The copper (I)-catalyzed direct synthesis of imines from amines under mild aerobic conditions is described. The method is applicable for the synthesis of various imines from corresponding amines such as benzylic, aliphatic, cyclic secondary, heteroaromatic species and the oxidative condensation of benzylamines with anilines extends the scope of the CuCl catalytic system. Noteworthy, solvent-free procedure, air as a benign oxidant, and the cheap and easy availability of the catalyst are the vital advantages of the method. Copyright
Nickel-magnesia catalysts: An alternative for the hydrogenation of 1,6-hexanedinitrile

, p. 202 - 209 (2007/10/03)
Two Ni-MgO systems were synthesized and characterized as Ni catalysts for the hydrogenation of 1,6-hexanedinitrile (adiponitrile) in the gas phase. All three catalysts displayed high selectivity to 1,6-hexanediamine, for a total conversion with a maximum
