  • Organomagnesium compounds
    Patent number: 4447369
    Abstract: A method of effectively increasing the settling rate of solid co-products from relatively viscous dialkyl magnesium solutions and thereby reducing the viscosity of such solutions wherein a small quantity of bis(cyclopentadienyl)magnesium or other cyclopentadienyl compound is added thereto. Alternatively, the bis(cyclopentadienyl)magnesium may be prepared in situ by adding cyclopentadiene directly to the dialkyl magnesium.
