## Abstract Treatment of acyclic γ‐bromopropargylic diols with tributylstannylated alkynes under palladium catalysis and microwave irradiation conditions gives high yields of the bis(alkylidene)cyclobutanediol derivatives and cyclobutenediols through an efficient 4‐__exo__‐__dig__ cyclocarbopallada
