WebCycloelimination of CO2 from 1 gives the transient species 2 (4n+2 electrons, Huckel transition state, thermally allowed). This is followed by either a [1,5] sigmatropic hydrogen shift (4n+2 electrons, Huckel t.s., thermal) to give 4, subsequently hydrolysed to 5, or by a p2s + p4s intramolecular cycloaddition to give the other product 3. mai accountingWebWhat does cycloelimination mean?A spoken definition of cycloelimination.Intro Sound:Typewriter - TamskpLicensed under CC:BA 3.0Outro Music:Groove Groove - Ke... mai achats kedgeWebSearch the Dictionary for More Terms.
