Finkel’shtein, E. Sh. published the artcileElectrophilic addition to methylenecyclobutane and bicyclobutylidene, HPLC of Formula: 20117-47-9, the publication is Neftekhimiya (1985), 25(1), 48-57, database is CAplus.
Title reaction of methylenecyclobutane (I) with ROH (R = Me, Et, Bu, 1-methylcyclobutyl, Ph, Ac, ClCH2CO, FCH2CO, CCl3CO, CF3CO) in the presence or absence of hexane or cyclohexane and/or 80% H2SO4 gave the corresponding ethers and esters II. PhOH gave 4-R1C6H4OH (R1 = 1-methylcyclobutyl) and 2,4,6-R13C6H2OH (same R1) as the major products. Analogous reactions of bicyclobutylidene with ROH (R = H, Me, Ac, CF3CO, Ph) gave bicyclo[3.3.0]octanes III (R2 = OH, OMe, OAc, O2CCF3, C6H4OH-4, resp.). I reacted with aqueous HCHO under these conditions to give 5,7-dioxaspiro[3.5]nonane, methanolysis which gave diol IV (R = H) (V) and IV (R = Me). Dehydrating V gave 1-vinylcyclobutene . The NMR and mass spectra of the products were interpreted.
