Abstract

An improved process for the preparation of solid Diels-Alder adducts of halogenated cyclopentadienes and mono- or diolefins is disclosed wherein the reactants are combined in an aqueous emulsion. The adducts are obtained in excellent yield and in an extremely fine particulate form. The new process avoids the use of organic solvents which are relatively costly, hazardous to use, and from which the adducts are usually obtained as relatively large crystals which require pulverization prior to use.
