Mizoroki–Heck cross-couplings of aryl halides in the presence of a palladium catalyst supported on a rasta resin bearing diphenylphosphanyl ligands are reported. In particular, we show that tiny amounts of soluble palladium species leached from the polymeric support catalyze the reaction. A one-pot two steps preparation of alkenes from aryl bromides using a Finkelstein halogen exchange reaction is...
Bifunctional palladated rasta resins 2b and 2c bearing both phosphino and basic amino groups have been successfully used for Mizoroki–Heck reactions between aryl iodides and alkenes without adding a soluble base. We have also shown that 2c can be easily regenerated after reaction and reused. To the best of our knowledge, this work represents the first use of a bifunctional palladated polymer for a...
