โœฆ Synopsis

By the palladium catalysis 2-carboethoxyethylzinc iodide reacts with aryl iodides and vinyl iodides or triflates to provide the coupling products (ethyl 3-arylpropionates and ethyl 4-pentenoates, respectively) in satisfactory yields. The similar coupling reaction is obserbed for the reaction with 3-carboethoxypropylzinc iodide.
