A general, regioselective synthesis of substituted benzocyclobutenedione monoacetals is reported.Palladium-catalyzed coupling of a variety of 4-chlorocyclobutenones with 3-(tri-n-butylstannyl)-3-cyclobutene-1,2-dione 2-(ethylene acetal) and heating up to
Synthesis of 2(5H)-furanones via oxidative ring expansion of 4-hydroxy-2-cyclobutenones

A new method to reduce cyclobutenediones towards 4-hydroxy-2-cyclobutenones was established. The latter compounds gave rise to new 5-halo-2(5H)-furanones by reaction with halogenating agents via a cationic ring-opening-ring-closure mechanism.
