Research Interests

The development of new catalytic systems that allow for rapid and selective transformations have a significant impact in the chemical industry, in particular in pharmaceutical, agrochemical, and fine chemical industry. In this context, organometallic compounds have become an established synthetic tool for the synthesis of useful molecules.

Our work focus on the development of new catalysts based on abundant and non-toxic metals for the synthesis of small-molecules of biological interest. We aim to develop atom economy processes with high selectivities, that exploit resources more efficiently and minime waste. Our activities are based on fundamental research focused on the synthesis of organometallic molecules and their reactivity studies. We are interested in applying organometallic compounds to catalysis as an approach to sustainable development.

Current areas of research in our group include:

  1. Development of new catalysts based on cheap and abundant metals for reduction and oxidation reactions including hydrogen transfer, and dehydrogenative-  and oxidative- coupling reactions.
  2. Exploit the fascinating properties of N-heterocyclic carbenes as ligands in organometallic chemistry.
  3. Study of metal-catalysed borrowing hydrogen reactions for the synthesis of pharmaceutical relevant intermediates.
  4. Explore new ways of waste valorisation, and better use of raw materials.
  5. Development of catalysis in water, as a key solvent for Green chemistry.

Catálise Organometálica (PT)

O desenvolvimento de novos catalisadores para a síntese de moléculas orgânicas tem um grande impacto na indústria farmacêutica e de química fina. Em particular, os catalisadores organometálicos permitem desenvolver processos muito eficientes e selectivos.

O nosso grupo de investigação trabalha no desenho e síntese de compostos organometálicos baseados em metáis baratos e no tóxicos para sua aplicação como catalisadores.
