Addition reaction involving diperoxyfumarate to form compounds having diperoxysuccinyl groups
Abstract
Abstract A DIESTER OF DIPEROXYFUMARIC ACID IS REATED AT ITS DOUBLE BOND WITH AN ORGANIC COMPOUND R-(X)S WHERE X IS A MONOALENT ATOM READILY ABSTRACTABLE BY A FREE RADICAL, E.G., HYDROGEN, CHLORINE OR BROMINE, AND R IS INERT TO THE PEROXYCARBONYL GROUPS OF THE DIPEROXYFUMARATE TO FORM AN ADDITION PRODUCT INCLUDING AT LEAST ONE DIESTER OF A SUBSTITUTED DIPEROXYSUCCINIC ACID. FOR EXAMPLE: TETRAHYDROFURAN AND DI-T-BUTYL DIPEROXYFUMARATE REACT AT ABOUT 0*C. TO FORM DI-T-BUTYL ALPHA-(2-TETRAHYDROFURYL) DIPEROCYSUCCINATE. POLYGLYOIS AND POLYVINYL ETHERS, ALCOHOLS, HALIDES, ETC. REACT TO GIVE POLYMERS HAVING PENDANT PAIRS OF PEROXYCARBONYL ESTER GROUPS IN GAMMA RELATIONSHIP TO EACH OTHER. THESE COMPOUNDS ARE OF SPECIAL INTEREST IN THE PREPARRATION OF BLOCK AND GRAFT COPOLYMERS.
