摘要：

Key ionic intermediates of the Heck reaction of arene diazonium salts have been intercepted and structurally characterized by ESI-MS/MS. The use of electrospray ionization enables the ionic species to be transferred smoothly to the gas phase. A catalytic cycle for this reaction involving all the Pd cationic species intercepted has been proposed (see scheme).
