    Abstract: The invention comprises divinylmagnesium, divinylcalcium, divinylstrontium and divinylbarium. They may be prepared by reacting the metal, preferably in a divided state, with divinylmercury under a dry inert atmosphere such as argon or nitrogen. If desired the reaction may be carried out in a solvent such as an aliphatic or aromatic hydrocarbon, an aliphatic ether containing 2 to 12 carbon atoms or an ether of ethylene or diethylene glycol. The reaction temperature is not critical but may be between 0 DEG and 100 DEG C. or higher depending on the solvent used. Methyl allyl carbinol is prepared by reacting divinylmagnesium with 1:2 propylene oxide and hydrolysing.
