Biphasic Aminations – Use of reactive ionic liquids in amination reactions

Curriculum Vitae:

In October 2011 Michael started his bachelor studies at the TU Dortmund and finished his bachelor thesis in August 2014 with the topic “Alkoxycarbonylation of 10-Undecenoic in thermomorphic Multicomponent Solvent systems” at the laboratory of industrial chemistry (TC). During his master studies from October 2014 to September 2016 he was supported by LANXESS AG as part of the “Deutschlandstipendium”. Throughout his master thesis at the chair of industrial chemistry in Dortmund with the topic “Investigations on Hydroaminomethylation of renewable 1,3-dienes – building blocks for surfactants on the basis of renewable resources” he established the first reported hydroaminomethylation of 1,3-dienes. For his thesis he was awarded with the “DECHEMA Studentenpreis” for a highly efficient study in the field of industrial chemistry.

Since May 2017 he is part of the chair of industrial chemistry under the leadership of Prof. Dr. Dieter Vogt in Dortmund as PhD student where he is focused on biphasic amination reactions.

Research Topic:

There are several different routes to produce amines in chemical industry. Unfortunately, these processes incorporate either an increased waste production or harsh reaction conditions due to the use of heterogeneous catalysts. In contrast to heterogeneous catalysts, the application of homogeneous catalysts allows for mild reaction conditions, higher selectivities and activities and increased atom efficiency. Unfortunately, the recovery of the expensive transition metal catalysts is difficult but necessary for the development of economically and ecologically feasible production processes. Through the use of a biphasic solvent system a highly active and selective reaction system is combined with an efficient recovery of the transition metal catalyst. Due to a loss of activity of the catalyst in classical biphasic systems (e.g. water/apolar organic solvent), owing to mass-transfer limitations, an alternative approach is needed.

A new class of ionic liquids is under investigation, which consists of substituted ammoniumcarbamates. Fortunately these ionic liquids can undergo amination reactions and act additionally as polar solvent phase, so that they can be defined as reactive ionic liquids.
