Palladium-catalyzed norbornene-carbon monoxide co-oligomerization initiated by aryl groups and terminated by double bond formation

Article abstract of DOI:10.1016/0022-328X(92)85082-8

The use of m-iodophenol as initiator in palladium-catalyzed norbornene-carbon monoxide oligomerization in the presence of potassium acetate unexpectedly leads to termination by double bond formation in spite of the limitations to β-H-anti elimination.The presence of endo products points to preliminary exo-to-endo isomerization through enolization.The X-ray structure of one stereoisomer (Ia) is given.
