Conversion of cyclo-octa-1,5-diene into 2,6-diacetoxybicyclo[3,3,0]octane by palladium(II) chloride–lead tetra-acetate in acetic acid; X-ray determination of the structure of the product
Abstract
Oxidation of cyclo-octa-1,5-diene by PdCl2–Pb-(OAc)4 in acetic acid gave as main product a 2,6-diacetoxybicyclo[3,3,0]octane which X-ray crystal analysis showed to be exclusively the di-endo-isomer.
