ABSTRACT:
In the transalkylation of tertiary amines, unexpected higher yields are achieved requiring substantially less catalyst and much shorter reaction times at lower reaction temperatures using a homogeneous catalyst in the presence of an alcohol solvent and carbon monoxide. The process may be exemplified by reacting triethylamine and tripropylamine in the presence of a homogeneous triosmiumdodecacarbonyl catalyst, ethanol, and carbon monoxide to prepare diethylpropylamine and ethyldipropylamine.
