The more cationic halogen containing compounds produced other products. Cobalt bis-allyliodide produced cis-polybutadiene and the even more cationic chromium, produced cyclododecatriene. Only with the more cationic system which introduced trans-structures, was cyclization and reduction of the metal able to intercept the polymerization reaction. Cyclization was not possible in the less cationic cobalt which produces all cis-polybutadiene nor was the hydride transfer possible with the less anionic chromium tris-allyl compound. [Pg.387]

Chromium tri-p-tolyl iodide, 2(C7H7)3CrI.C2H5.O.C2H5.— Chromium tri-p-tolyl hydroxide is isolated by a similar method to that used for the corresponding phenyl compound, and by means of an excess of aqueous potassium iodide is converted into the iodide. This melts with decomposition at 115° to 119° C., is soluble in alcohol, nitrobenzene or chloroform, insoluble in cold benzene, ethyl acetate or ether. [Pg.271]

A number of substituted benzenes, naphthalenes, indans, pyridmes, and indoles form arene(tricarbonyl)chromium complexes upon thermolysis under an inert atmosphere, usually in a high boiling ether, or by irradiation of the arenes in the presence of chromium hexacarbonyl. The complexes are relatively air-stable and can usually be stored for long periods in the absence of light. Somewhat milder conditions can be used by transfer of the chromium tricarbonyl group from preformed naphthalene(tricarbonyl)chromium, tris(L)tricarbonyl chromium (L = acetonitrile, ammonia, pyridine), or tricarbonyl( -l-methylpyrrole)chromium. Enan-tiomerically pure arene(tricarbonyl)chromium complexes having two different substituents, either ortho or meta can be prepared conveniently by classical resolution of racemic... [Pg.3235]

Other studies of considerable interest have been performed on such systems 33, 57). Pettit et al. (30) had first suggested that the chromium tri-carbonyl-complexed benzyl cation was extraordinarily stable. Trahanovsky and Wells (80) have quantitatively estimated the difference of pK + for...

Detailed kinetic measurements have not been carried out on the soluble allylic compounds from Group IV, V and VI transition metals but rates depend on the transition metal, the presence and number of halogen atoms, and the structure of the allylic grouping [231]. Chromium tris(2-methallyl) was found to be among the more active initiators. Halogen substitution for allyl groups reduced the activity of chromium... [Pg.201]
