Abstract
Disclosed are methods of producing di-, tri- or tetrabenzyl-metal compounds comprising combining a metal salt with a (benzyl)nMgX2-n compound at from less than 30° C., wherein n is 1 or 2 and X is a monoanionic group; wherein the combining takes place in a diluent mixture comprising from 0 to 80% by volume of an ether diluent and a diluent selected from the group consisting of aromatic diluents, halogenated hydrocarbon diluents, and mixtures thereof. The methods are characterized by employing various mixtures of diluents, and in some cases, minimal to no ether diluent.
Claims24
A method of producing a di-, tri- or tetrabenzyl-metal compound comprising combining a metal salt with a (benzyl)nMgX2-n compound, wherein n is 1 or 2 and X is a monoanionic group;
- wherein the combining takes place in a diluent mixture comprising from 0 to 80% by volume of the diluent mixture of an ether diluent, and a diluent selected from the group consisting of aromatic diluents, halogenated hydrocarbon diluents, and mixtures thereof.
A method of preparing a metal compound comprising reacting a neutral ligand with the di-, tri- or tetrabenzyl metal compound;
- wherein the di-, tri- or tetrabenzyl metal compound is made by combining a metal salt with a (benzyl)nMgX2-n compound, wherein n is 1 or 2 and X is a monoanionic group;
- wherein the combining takes place in a diluent mixture comprising from 0 to 80% by volume of an ether diluent and a diluent selected from the group consisting of aromatic diluents, halogenated hydrocarbon diluents, and mixtures thereof.
