Transmetalation process

Claim 1

A TRANSMETALATION PROCESS FOR PREPARING ALIPHATIC POLYOLEFIN HYDROCARBONS CONTAINING AT LEAST 8 CARBON ATOMS AND ORGANO ALKALI METAL COMPOUNDS SIMULTANEOUSLY, WHICH COMPRISES REACTING 8A) A DIALKALI METAL POLYOLEFIN COMPOUND CONTAINING AT LEAST 8 CARBON ATOMS WITH (B) AN ACTIVE HYDROGEN-CONTAINING ORGANIC REAGENT CAPABLE OF FORMING AN ALKALI METAL DERIVATIVE THEREOF, SELECTED FROM THE GROUP CONSISTING OF (1) ARYL HYDROCARBONS, (2) ACETYLENIC HYDROCARBONS, (3) CYCLODIENYL HYDROCARBONS, (4) ARYL ETHERS, (5) ARYL FLUORIDES, (6) ALKALI METAL SALTS OF MONOCARBOXYLIC ACIDS CONTAINING BETWEEN ABOUT 2 THROUGH 20 CARBON ATOMS, AND (7) SUBSTITUTED HYDROCARBONS, WHEREIN THE SOLE SUBSTITUENT IS A NITRILO GROUP; WHICH REAGENTS ARE FREE FROM FUNCTIONAL GROUPS WHICH ARE REACTIVE TOWARD ALKALI METALS, SAID DIALKALI METAL POLYOLEFIN HYDROCARBON BEING AN OCTA TO DODECA POLYENE AND HAVING AN UNSATURATION RANGING FROM DIENES TO TETRAENES, SAID REACTION BEING INITIATED AT A TEMPERATURE NOT GREATER THAN ABOUT 40* C. IN A REACTION MEDIUM CONSISTING ESSENTIALLY OF A SOLVENT SELECTED FROM THE GROUP CONSISTING OF ETHERS, ACETALS AND TERTIARY AMINES; AND RECOVERING SAID POLYOLEFIN HYDROCARBON AND AN ALKALI METAL COMPOUND OF SAID ORGANIC REAGENT AS PRODUCTS OF THE REACTION.
