Frontispiz: Mangan(I) katalysierte ortho C–H-Allylierung von Benzoesäuren
Graphical Abstract
Allylation. In their Communication (e202301839), Lukas J. Gooßen et al. report a simple manganese catalyst for the ortho-C−H allylation of benzoic acids. The reaction can be combined with an in situ decarboxylation, giving access to allylarenes in substitution patterns that are otherwise hard to obtain.
