A copper‐promoted oxyalkylation of alkenes with alkylnitriles has been developed. The protocol provides rapid access to phthalides (γ‐lactones) or isochromanones (δ‐lactones) via the formation of a C(sp3)C(sp3) and a C(sp3)O bond with the generation of up to two quaternary carbon atoms. Mechanistic studies suggest that this reaction is initiated by the formation of the C(sp3)C(sp3) bond rather than
