Zusammenfassung:	1,150,665. Carboxylates and alkoxides of di- and trivalent metals. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. 6 May, 1966 [6 May, 1965], No. 20172/66. Heading C2C. [Also in Division C3] Carboxylates, alkoxides of di- and trivalent metals are obtained by heating a compound of the formula with a compound of the formula YO-M-Z at 60-300 C. under anhydrous conditions, wherein M1 is a trivalent metal of Group III-VI or VIII, M is a divalent metal or metal radical of Group I, II, IV-VIII, Z is a carboxylic acyloxy radical or the group -OR 3 , one of X and Y is a carboxylic acyl radical and the other is a group R 4 , and R 1-4 are monovalent hydrocarbon radicals, the reaction being continued until at least 1% mol. of the theoretical quantity of the by-product ester XOY has been formed. When the atomic ratio M1: M is 2, the product is believed to have the formula where R is a hydrocarbon radical, but if less than the theoretical amount of ester XOY is formed, the product may be The ratio of trivalent metal reactant to divalent metal reactant may be in the range 0À01-100, preferably 0À1-10. The reaction is preferably effected in an inert solvent, e.g. hydrocarbons, halogenated hydrocarbons, which may also act as an entraining agent for the by-product ester. The product may also be separated from the ester at the end of the reaction by, e.g., extraction. The metal products are usually soluble in hexane. Specified trivalent metals are Fe, Mo, Cr, V, Ti, Zr, B, Ga, In, Tl, Bi and Sc. Specified divalent metals and radicals are Be, Mg, Zn, Cd, Ca, Sr, Ba, Cu, Sn, Ti, V, VO, TiO, Pd, Pt, Cr, UO 2 , ZrO, Ni, Co, Fe and Mn. The carboxylate reactant may be prepared in situ from the appropriate acid or anhydride and the compounds M1(OR) 3 and M(OR) 2 . The -OR groups in the product may be replaced by different -OR radicals by heating with an alcohol or phenol which is less volatile than ROH. Numerous examples are provided, most of which relate to Zn/Al compounds. The products are used as catalysts in the polymerization of 1,2- and 1,3-epoxides (see Division C3).
