✦ Synopsis

Onsager (Oslo, Norway)

reported the dimerization of propene to a mixture of cis-2-hexene, 2,3-dimethyl-l-butene.

2-methyl-1 -pentme, and 4-methyl-1 -pentene with a catalyst composed of tetramethylcyclobutadienenickel dichloride, ethylaluminum dichloride, and tri-n-butylphosphine. C. F. Kohl1 (Amsterdam, Netherlands) described the synthesis of vinyl esters by the PdClz-catalyzed reaction of ethylene and sodium acetate in glacial acetic acid. J . M . Locke (Southampton, England) described the hydrogenation of unsaturated polymers, n-dodecene, styrene, or diphenylacetylene using a catalyst prepared by the addition of bis(isopropylsa1icylato)nickel to n-butyllithium in tetrahydrofuran or diglyme. J. D. Littlehailes (Runcorn, England) reported the hydrodimerization of acrylonitrile to give an almost quantitative yield of adiponitrile with sodium amalgam and water in the presence of quaternary ammonium salts.
