A simple manganese catalyst sets new standards in the ortho-C−H allylation of benzoates, by allowing nearly complete selectivity for mono- over competing di-allylation. The reaction can be combined with an in situ decarboxylation, giving access to allylarenes in substitution patterns that are otherwise hard to obtain. The scope of the protocol is demonstrated by 44 diverse examples.
