Application of 31608-22-7, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature 31608-22-7, C9H17BrO2. A document type is Article, introducing its new discovery.
Oxidation of cyclopentadienes 1a-1j, which were prepared by alkylation of cyclopentadienyl anion with the corresponding alkyl bromides, with pyridinium chlorochromate (PCC) gave the 2-cyclopentenones 2a-2j respectively in 10-15percent yields.Reaction of 3 and 5 with PCC gave the spiro compounds 4 and 6 respectively in 75-80percent yields. Key Words 3-Substituted 2-cyclopentenones; Cyclopentadienes; PCC.
