Abstract
Abstract A novel process is described for the preparation of novel organic solutions of organooxy magnesium compounds of low viscosity, which solutions are formed in the presence of at least 5 mol % based on the magnesium compound of an organooxy compound of a transition metal of Groups IV through VI of the Periodic Table.
