The first steps, believed to be involved in the highly enantioselective copolymerization of styrene and carbon monoxide to poly[1‐oxo‐2‐phenylpropane‐1,3‐diyl] with phosphinodihydrooxazole‐palladium(II) complexes, were investigated. The insertion of carbon monoxide into [Pd(Me)(PˆN)(solvent)] TfO (PˆN = ( S )‐2‐[2‐(5 H ‐benzo[ b ]phosphindol‐5‐yl)phenyl]4‐benzyl‐4,5‐dihydrooxazole (1)) and of styrene into [Pd(Me)(PˆN)(solvent)] TfO were highly regioselective (alkyl and acyl substituents trans to N); moreover, the olefin insertion took place with essentially complete enantioface discrimination.
