✦ Synopsis

An efficient heterogeneously palladium catalysed procedure for the vinylation of aryl iodides and bromides is reported. Using common reaction conditions (Pd/C 2 mol %, AcONaÁ3H 2 O, NMP or NMP/H 2 O), good to complete conversions (40-100%) with high selectivities (79-100%) towards the expected vinylaromatic were achieved.
