The intramolecular frustrated phosphane/boraneLewispair Mes2PCH2CH2B(C6F5)2 (3) reacts with acetyl chloride to give a 1 : 1 mixture of the FLP‐ketene adduct, 6a, and the FLP‐HCl addition product, 7. Similarly, the acyl chlorides phenylacetyl chloride and isobutyryl chloride react with 3 to give the respective substituted FLP ketene adducts, 6b and 6c, with HCl elimination.
