<jats:title>Abstract</jats:title> <jats:p>The 1,5-sigmatropy of 3,3-diphenyl-3,3a-dihydrocyclohepta[b]furan-2-one was examined in dibutyl ether to 1600 bar at 130 °C. The rearrangement was slightly accelerated with pressure, and was different to the pressure effect of 1,5-sigmatropy of cyclopentadienes. The activation volume was in the range of the concerted process, but its transition state was as loose as those biradical-like.</jats:p>
