Abstract: The present invention relates to the synthesis of oxide materials, layered double hydroxide materials (LDH materials), hydroxide materials and carbonate-based materials with high surface area and controlled size and nano-particle shape as well as the formation of mixed metal hydroxides and hydroxycarbonates with high surface areas which can serve as precursor materials to deliver oxide materials after thermal treatment. The process of the invention relates to the preparation of oxide materials on the base of metal alkoxides which are hydrolyzed under highly controlled conditions in the presence of high-boiling and low-boiling alcohol whereby the low boiling-alcohol has to act as co-solvent.

Abstract: In a process for preparing an alkalimetalor alkaline earth metal salt of an
α,β -ethylenically unsaturated carboxylic acid, a)a transition metal-alkene complex is reacted with CO
2 to give a metallalactone, b)the metallalactone is reacted with a base to give an adduct of the alkalimetal or alkaline earth metal salt of the
α,β -ethylenically unsaturated carboxylic acid with the transition metal complex, and c)the adduct is reacted with an alkene to release the alkalimetalor alkaline earth metalsalt of the
α,β -ethylenically unsaturated carboxylic acid and regenerate the transition metal-alkene complex. The baseis selected from alkalimetal or alkaline earth metal hydroxides and alkali metal or alkaline earth metal superbases.The alkene is, for example, ethene. The transition metal complex comprises, for example, nickel and a bidentate P,P, P,N, P,O or P,carbene ligand, such as 1,2-bis(di-
tert -butylphosphino)ethane.
