| abstract | 1330549 Organometallic compounds of Ca, Sr and Ba GENERAL TIRE & RUBBER CO 20 Aug 1971 [3 Sept 1970] 39248/71 Heading C2J [Also in Divisions C1 and C3] Organometallic compounds of calcium, strontiurn and barium in which the metal is joined by an ionic carbon to metal bond to one of xanthene, cyclopentadiene, indene, 9-phenylxanthene, triphenylmethane, phenylacetylene, 1,3,3 - triphenylpropene, 9 - phenylfluorene, 9- (alpha - naphthyl)fluorene, 9 - (2 - methoxyphenyl)fluorene, 9 - (alpha - naphthyl)xanthene, 9 - (2 - methoxyphenyl)xanthene, bis - (2- methoxyphenyl)methane, 1,1,2-triphenylethane and 1,1-diphenylalkanes having C 1-10 alkane groups, or mixtures thereof, are prepared by reacting the metal, usually in finely-divided state, with the organic compound at - 90‹ to 150‹ C. under anhydrous conditions in an aprotic polar solvent such as a peralkyl phosphoramide (especially hexamethyl phosphoramide), dialkoxyalkane, dialkoxypolyoxyalkane, dialkyl ether, peralkyl alkylene polyamine or a heterocyclic ether, optionally mixed with up to 90% of a liquid hydrocarbon. In examples, dixanthenyl barium (mixed with the Ba salt of o-hydroxy diphenylmethane) and strontium, diindenyl calcium and barium, bis-(triphenylmethyl)barium and bis - (diphenylmethyl)- barium are prepared. Solutions of the compounds in aprotic polar solvents are used as catalysts for polymerization of vinyl and oxirane monomers. |
