Resumo
The Heck reaction between E- and Z-enoates and iodobenzene was studied in the presence
of Pd(OAc)2. The stereochemistry in resulting adducts was dependent on the enoate geometry
(stereospecific reaction). Best yields were obtained from Z-isomers in acetone using Ag2CO3 as
base. The main cationic palladium intermediates possibly involved in the catalytic cycle could
be intercepted and characterized by electrospray ionization mass spectrometry (ESI-MS). The
