New palladium carbene catalysts for the Heck reaction of aryl chlorides in ionic liquids.
[reaction: see text] The Heck reaction of aryl chlorides was investigated in the presence of defined monocarbenepalladium(0) complexes. Activated and nonactivated aryl chlorides provide the corresponding cinnamic esters and stilbenes in (n)Bu(4)NBr as a ionic liquid in good to excellent yields.
