Grignard reactions in presence of cyclic ethers

Claim 1

A METHOD OF PREPARING ORGANOSILANES WHICH COMPRISES REACTING AT A TEMPERATURE O F ABOUT 20 TO 80* C., A COMPOUND Q SOLUTION OF AN ORGANOMAGNESIUM CHLORIDE REAGENT SELECTED FROM THE CLASS CONSISTING OF ARYLMAGNESIUM CHLORIDES, VINYLIC MAGNESIUM CHLORIDES, ACTIVEHYDROGEN FREE HETEROCYCLIC MAGNESIUM CHLORIDES WITH A SILICON COMPOUND OF FORMULA AA''A"SIX, WHEREIN X IS SELECTED FROM THE GROUP CONSISTING OF HALOGEN AND OR GROUPS, A, A'' AND A" ARE THE SAME OR DIFFERENT FROM EACH OTHER, AND ARE SELECTED FROM THE CLASS CONSISTING OF HYDROGEN, HYDROCARBON GROUPS, HALOGEN AND OR GROUPS, WHEREIN R IS A HYDROCARBON RADICAL IN THE PRESENCE OF AN INERT HYDROCARBON SOLVENT, AND RECOVERING SAID SILANES, SAID COMPOUND Q BEING AN ETHER CONTAINING FROM 5 TO 6 ATOMS IN THE RING AND WHEREIN (A) THERE IS ONLY ON OXYGEN ATOM IN THE RING, (B) THE OTHER RING ATOMS ARE CARBON, (C) ONE RING CARBON SEPARATED FROM THE OXYGEN ATOM IN THE RING BY TWO CARBON ATOMS MAY BE REPLACED BY AN ALKYL SUBSTITUTED NITROGEN ATOM, (D) THE RING CONTAINS NOT MORE THAN ONE DOUBLE BOND, (E) AT LEAST ONE CARBON ATOM ADJACENT THE OXYGEN ATOM IN SAID RING BEING FREE OF ANY SUBSTITUENTS OTHER THAN HYDROGEN, (F) SAID ETHER CONTAINS NO SUBSTITUNET WHICH REACTS WITH ORGANOMAGNESIUM CHLORIDES OR WITH OTHER COMPONENTS OR PORDUCTS OF THE REACTION MIXTURE.
