α‐Halogenoacetanilides (X=F, Cl, Br) were examined as H‐bonding organocatalysts designed for the double activation of CO bonds through NH and CH donor groups. Depending on the halide substituents, the double H‐bond involved a nonconventional CH⋅⋅⋅O interaction with either a HCXn (n=1–2, X=Cl, Br) or a HCAr bond (X=F), as shown in the solid‐state crystal structures and by molecular modeling.
