Abstract
Dimethyl sulphate is reacted under substantially anhydrous conditions and at low temperature with magnesium in a solvent comprising tetrahydrofuran, tetrahydropyran or an alkyl derivative thereof, or a polyethylene glycol ether of formula R.(OCH2.CH2)vOR1 wherein R and R1 represent the same or different alkyl groups and n is an integer. Preferably R-R1 each contain not more than 4 carbon atoms and n is 2 or 3, e.g. diethylene glycol diethyl and dibutyl ethers. The reaction is carried out under a nitrogen atmosphere and it may be activated by an iodine crystal. Insoluble magnesium methyl sulphate is precipitated, usually not in large quantities. It may be eliminated by filtration or decantation. The product solution may be used in Grignard reactions without isolating the products. In the examples magnesium and dimethyl sulphate are reacted in (1) tetrahydrofuran, (2) tetrahydropyran and (3) diethylene glycol diethyl ether.
