A copper-catalyzed conjugate silylation of various cyclobutenone derivatives with Me2PhSiZnCl ? 2LiCl or (Me2PhSi)2Zn ? xLiCl (x≤4) to generate β-silylated cyclobutanones is reported. Trapping the intermediate enolate with ClP(O)(OPh)2 affords silylated enol phosphates that can be further engaged in Kumada cross-coupling reactions to yield silylated cyclobutene derivatives.

The reaction of 2,2-dichloro-3-cyclopropylcyclobutanones with potassium hydroxide was studied.The direction of the reaction depends on the concentration of the potassium hydroxide; with a 2percent solution of potassium hydroxide 4,4-dichlorobutyric acids are formed with yields of up to 80percent, and with a 15percent solution of potassium hydroxide 5-hydroxydihydro-2-furanones are formed with yields of up to 80percent.Proposals are made about mechanism of formation of 5-hydroxydihydro-2-furanones.

3-Methyl- (8a) and 3-cyclopropyl-1-cyclobutenyl nonaflate (8b) as well as 2-cyclopropyl-1-cyclobutenyl nonaflate (12) and the parent 1-cyclobutenyl nonaflate (3) were synthesized from the corresponding cyclobutanones and nonafluorobutanesulfonic anhydride (10).The solvolysis rates and the product compositions of the solvolyses in trifluoroethanol and trifluoroethanol/water mixtures were determined.All 1-cyclobutenyl nonaflates solvolyze via a SN1 mechanism involving the intermediate nonclassical 1-cyclobutenyl cation, which is additionally stabilized by the substituents in the 3-position.
