Aluminacycloalkene moiety containing compounds and their preparation and uses

Abstract

Abstract NONIONIC COMPOUNDS IN WHICH AN ALUMINUM ATOM IS PART OF AN OLEFINICALLY UNSATURATED RING SYSTEM ARE PREPARED BY CAUSING INTERACTION AMONG ALUMINUM, A CONJUGATED DIENE AND A HYDROCARBON ALUMINUM HYDRIDE IN THE PRESENCE OF A SUITABLE LEWIS BASE SUCH AS 1,4-DIOXANE OR N-METHYL PYRROLIDINE. THE RESULTING CYCLIC ORGANO-ALUMINUM COMPOUND IS USEFUL IN THE SYNTHESIS OF OLEFINS AND BRANCHED CHAIN ALKANOLS. THUS BY SUBJECTING THE CYCLIC ORGANO-ALUMINUM COMPOUND TO HYDROLYSIS, ONE OR MORE OLEFINS MAY BE PRODUCED. TO PREPARE BRANCHED CHAIN ALKENOLS, THE CYCLIC ORGANO-ALUMINUM COMPOUND IS REACTED WITH A CLEAVALBE CYCLOPARAFFINIC MONOETHER HAVING A 3, 4 OR 5 MEMBERED RING. THEREUPON THE REACTION MIXTURE IS SUBJECTED TO HYDROLYSIS. THE FOLLOWING NOVEL COMPOUNDS WERE PREPARED BY THIS PROCEDURE: 1-CHLOROMETHYL-3,4-DIMETHYL-4-PENTEN-1-OL 1-CHLOROMETHYL-3,3-DIMETHYL-4-PENTEN-1-OL 2,2-BIS(CHLOROMETHYL)-4,5-DIMETHYL-5-HEXEN-1-OL 2,2-BIS (CHLOROMETHYL)-4,4-DIMETHYL-5-HEXEN-1-OL 1,5,5-TRIMETHYL-6-HEPTEN-1-OL 1,5,6-TRIMETHYL-6-HEPTEN-1-OL 4,5,6-TRIMETHYL-6-HEPTEN-1-OL 2,2,3-TRIMETHYL-5,5-BIS (CHLOROMETHYL) TETRAHYDROPYRAN.
