Manganese(I)‐Catalyzed Substitutive C−H Allylation

The first manganese(I)-catalyzed C−H allylations with ample scope were achieved by carboxylate assistance. The highly selective C−H/C−O functionalizations proved viable with densely substituted allyl carbonates, and the organometallic C−H allylation strategy set the stage for expedient late-stage diversification with excellent levels of positional selectivity.
