Synthesis of Tertiary Fatty Amines in Water: The Dual Role of Dimethylamine as Reagent and Phase Mediator in the Homogeneously Catalyzed Fatty Alcohol Amination

“…It is already applied in industry, for instance, for the synthesis of methyl amines from ammonia and methanol. Unfortunately, this strategy, and particularly the very active but not selective heterogenoeus catalyst which is used for dimethylamine (DMA) synthesis, cannot be applied for the highly desired synthesis of tertiary dimethyl alkyl amines, since DMA itself would be converted into to methyl- and trimethylamine under those conditions, thus giving rise to a wide range of possible coupling and consecutive products resulting in massive downstream issues. − Moreover, fatty alcohols are even more demanding, since these usually cannot react selectively in the gas phase due to their very high vapor pressure, which excludes heterogeneous catalysts.…”
