description Halogenovinyl-substituted tetrahydrofuran-2-ones of the formula are prepared by reacting a peracid such as peracetic, perpropionic or m-chloroperbenzoic acid with a halogenvinyl-substituted cyclobutanene of the formula in which R1 to R8 can be hydrogen, halogen, cyano or various organic radicals, or in pairs can make up a ring. Products wherein R3 is not hydrogen or R1 is not halogen are new. The products are useful as intermediates in making insecticides.
