  • Combinatorial chemistry (25.20%)

What were the highlights of his more recent work (between 2017-2021)?

  • Catalysis (56.40%)
  • Medicinal chemistry (16.40%)
  • Combinatorial chemistry (25.20%)

In recent papers he was focusing on the following fields of study:

His main research concerns Catalysis, Medicinal chemistry, Combinatorial chemistry, Regioselectivity and Visible spectrum. His work on Rhodium as part of general Catalysis research is often related to Ionic bonding, thus linking different fields of science. His Medicinal chemistry study integrates concerns from other disciplines, such as Alkylation, Ruthenium, Bond cleavage, Indole test and Aryl.

His biological study spans a wide range of topics, including Reagent, N-fluorobenzenesulfonimide, Alkyne and Aryne. His work deals with themes such as Ionic liquid, Iodobenzene, Amine derivatives and Copper, which intersect with Regioselectivity. His Annulation study deals with the bigger picture of Organic chemistry.

Between 2017 and 2021, his most popular works were:
