Amination of aliphatic alcohols with urea catalyzed by ruthenium complexes: effect of supporting ligands
In the present study, ruthenium-catalyzed amination of alcohols by urea as a convenient ammonia carrier in the presence of free diphosphine ligands has been described. A number of ruthenium-phosphine complexes have been studied among which, [(Cp)RuCl(dppe)] was found as an efficient catalyst for alcohol amination reaction. The crystal structures of two new half-sandwich ruthenium complexes, [(Cp)RuCl(dppe)] and [(C6H6)RuCl2(PHEt2)], were determined by X-ray crystallographic analysis. Also the effect of using different supporting phosphines, ratio of raw materials and reaction temperature on conversion and selectivity was investigated. Under optimum reaction conditions high conversion (98percent) and chemo-selectivity toward secondary amines were obtained.

Conversion of Primary Amines to Symmetrical Secondary and Tertiary Amines using a Co-Rh Heterobimetallic Nanocatalyst
Symmetrical tertiary amines have been efficiently realized from amine and secondary amines via deaminated homocoupling with heterogeneous bimetallic Co2Rh2/C as catalyst (molar ratio Co:Rh=2:2). Unsymmetric secondary anilines were produced from the reaction of anilines with symmetric tertiary amines. The Co2Rh2/C catalyst exhibited very high catalytic activity towards a wide range of amines and could be conveniently recycled ten times without considerable leaching. (Figure presented.).

Ruthenium-catalyzed deaminative redistribution of primary and secondary amines
A ruthenium-hydride complex, [Ru(H)(Cl)(CO)(PCy3)2], was found to be active in the highly selective redistribution of primary and secondary amines bearing an α-hydrogen atom. This new deaminative coupling of amines enables the highly selective synthesis of secondary amines from primary amines and of tertiary amines from secondary amines with the evolution of ammonia. A preliminary mechanistic view of this novel reaction based on catalytic experiments using NMR methods confirms the synthetic observations.

Process for the preparation of nonadecanediols
The present invention relates to a process for the preparation of nonadecanediols by the hydroformylation of oleyl alcohol. Rhodium and salts of sulfonated or carboxylated triarylphosphines, which are soluble in organic media and insoluble in water, are used as hydroformylation catalysts. The hydroformylation product is then treated with a diluted solution of a base dissolved in water, the aqueous phase separated and the hydroformylation product treated with hydrogen at elevated temperature in the presence of a hydrogenation catalyst.
