A team of researchers led by Prof. Frank Glorius and Michael Teders from the University of Münster and by Prof. Dirk Guldi from the University of Erlangen-Nuremberg have presented a new chemical reaction path which may prove to be of interest both for research and for the production of active ingredients in medicines. The new reaction leads to a splitting of bonds between two sulphur atoms. The chemists use a light-driven catalysis method (photocatalysis) to enable it. The results of the researchers’ work have been published in the latest issue of the journal Nature Chemistry (advance online publication).
