  Carbonylative Heck Reactions Using CO Generated ex Situ in a Two-Chamber System

  摘要：

  A carbonylative Heck reaction of aryl iodides and styrene derivatives employing a two-chamber system using a stable, crystalline, and nontransition metal based carbon monoxide source is reported. By applying near-stoichiometric amounts of the carbon monoxide precursor, an effective exploitation of the hazardous CO gas is obtained affording chalcone derivatives in good yields. Application to isotope labeling, incorporating (13)CO, was further established.
