Abstract

NEW MATERIAL:2-Carboxy-3, 4-dimethyl-7-isopropylidene-bicyclo[4, 2, 0]-oct-3- en-8-one of formula I.
USE: Useful as a material for preparation of a monoglycidyl ester which is a diluent of epoxy resin useful as a casting material, an adhesive, a resin additive, and a reinforcing material of fibers and paper. Useful as a chelating agent, as a starting material of complex compounds which are useful as anti-corrosive agents, organic pigments, and resin additives. Also useful as a starting material of pesticides and pharmaceuticals, and as a raw material of functional polymers.
PROCESS: The compound of formula II is heated at 100W200°C for 0.5-several hrs in the presence or absence of a solvent, e.g. toluene, in the presence of an acid catalyst, e.g. boron trifluoride.etherate, aluminum chloride etc. The isomerized precipitate is purified from methyl isobutyl ketone solution, e.g. by recrystallization, to give the compound of formula I.
