摘　　要：A palladium-catalyzed cyclobutenation of readily available aryl chlorides and norbornene derivatives is reported here.Under the optimum reaction conditions,various valuable benzocyclobutene derivatives were prepared efficiently via Heck-Catellani reaction.The key is the employment of bulky t-Bu_(3)PHBF_(4) phosphine ligand which promoted C-C reductive elimination from the palladacycle.
