In this issue, A. E. Wendlandt and S. S. Stahl review the quinone-catalyzed selective oxidation of organic molecules. How can the stoichiometric use of quinones be replaced with more desirable reagents? In a Minireview, B. Yang et al. discuss non-conjugated cross-linked polymer dots without fluorophores. The Highlight deals with natural-product therapeutics against parasitic diseases (C. Hertweck).

In the Communications section, A. Schaller et al. present dirigent proteins from cotton for the synthesis of gossypol (see picture). L. Lindfors et al. uncovered a nuclei breeding factory responsible for the secondary nucleation in crystal growth. J. Lee et al. report on the electrocatalytic production of C3-C4 compounds by conversion of CO₂ on a biphasic Cu₂O-Cu catalyst. W. Zhang et al. succeeded in the direct trifluoromethylthiolation and perfluoroalkylthiolation of C(sp³)–H bonds.
