Abstract
An organometallic addition compound in which the metallic element has an ionization energy not greater than that of calcium and the organo portion is derived from an organic compound containing one or more linkages whose bond order is greater than unity and having a sufficiently high affinity for electrons to form an addition compound without immobilizing any transferred electrons with the formation of an ion, is prepared by direct impingement in high vacuo of the metallic element vapour on the organic compound, or by bringing together the metallic element and the organic compound in the presence of an inert solvent in an oxygen-free atmosphere and the reaction product is either treated to remove excess organic compound and solvent by elutriation, preferably followed by evaporation of any remaining solvent in vacuo, and any unreacted metal may be removed mechanically from the desired product, or filtered in the complete absence of air and moisture, the filtrate is cooled, and the precipitated desired product is washed with a liquid in which it is insoluble to free it from solvent and dried. The organometallic addition compound formed by any of the processes referred to above may be subsequently treated to vary the ratio of metal to organic compound, i.e. by elutriation and filtration followed by removal of the solvent in vacuo, or by sublimation of part of the organic compound in vacuo at a temperature below that at which the addition compound breaks down. The metal in the organometallic addition compound may be lithium, sodium, potassium, rubidium, caesium, calcium, strontium, barium, lanthanum, indium or praseodymium. The organic compound may be an aromatic compound with three or more condensed rings, a long-chain aliphatic hydrocarbon having conjugated double-bond systems -particularly such an aliphatic hydrocarbon in which there are one or more rings as substituents, or a cycloaliphatic hydrocarbon having a ring of eight or more carbon atoms and a system of conjugated double bonds. Analogous compounds in which one or more carbon atoms are replaced by nitrogen atoms may also be used. Specific organic compounds mentioned are tetraphenylethylene, 1 : 1-bis-diphenylethylene, p-terphenyl, diphenylfulvene, bis-diphenylene-ethylene, anthracene, 11,3-triphenyl-indene, 2,6 - dimethyl - 4 - methylene - hepta - 2,5 - diene, 1 - diphenylene - 4 - phenyl - buta - 1,3 - diene, tetra - (p - dimethylaminophenyl)-ethylene, 1 - cyano - 1,2,2 - triphenylethylene, 1,3,5 - triphenyl - 2,4 - diazapenta - 1,4 - diene, 5 - phenylacridine, 2,4,5 - triphenyl - 4,5 - dihydroglyoxaline, dibenzopyrazine and dixanthylene. In a number of preparations, organometallic addition compounds are prepared from sodium, potassium and lithium and anthracene, and lithium and cyclo-octatetraene.
