prof. dr. K. Barta
ERC starting grant of 1.5 M eu awarded to support research activities in the Barta group!
Dr. Katalin Barta of the Synthetic Organic Chemistry group (Stratingh Institute for Chemistry) has been awarded an ERC Starting Grant of 1.5 million EUR. During this research she will develop novel, fully sustainable catalytic methods for the conversion of renewable resources to industrially relevant bulk and fine chemicals. The approach combines several disciplines including homogeneous and heterogeneous catalysis in order to address key fundamental challenges in the field . The ERC Starting Grant enables researchers to establish their team to further develop their research lines.

Amines are among the most valuable classes of compounds in chemistry, omnipresent in natural products, in particular alkaloids, and widely used as pharmaceuticals, agrochemicals, lubricants and surfactants. Therefore, the selective conversion of C-O bonds into C-N bonds to form amines is one of the most important chemical transformations for the production of bulk and fine chemicals. An attractive atom economic4 way of carrying out such transformations is the direct N-alkylation of simple amines with alcohols through the borrowing hydrogen strategy. Surprisingly, this transformation was limited to catalysts that use precious noble metals such as Ir and Ru. Novel, efficient catalysts, based on inexpensive and abundant metals are desired. We recently reported on the direct alkylation of amines using a wide range of alcohols, with a well-defined homogeneous iron-cyclopentadienone complex. The scope of this new methodology includes the selective monoalkylation of anilines and benzyl-amines with a wide range of alcohols as well as the use of diols in the formation of five-, six- and seven- membered nitrogen heterocycles, which are privileged structures in numerous pharmaceuticals. These studies are a first step towards more sustainable, direct waste-free alcohol to amine transformation where water is the only by-product; and will enable the development of a range of new catalyst structures using abundant iron.
