SYNTHESIS AND THERMAL TRANSFORMATIONS OF BICYCLOALKENES CONTAINING A METHYLENECYCLOPROPANE FRAGMENT

The previously undescribed 8-methylenebicyclooct-2-ene (II) and 9-methylenebicyclonon-4-ene (IV) were synthesized by the dehydrohalogenation of 8-methyl-8-chlorobicyclooct-2-ene and 9-methyl-9-chlorobicyclonon-4-ene.It was established that the hydrocarbon (II) is thermally labile, whereas the hydrocarbon (IV) does not change right up to 300 deg C.The thermal transformations of the hydrocarbon (II) and its isomeric bicyclonona-1,6-diene (III) at 100 - 180 deg C were investigated.At 100 deg C a pseudoequilibrium is established between these hydrocarbons.The final and only products from the transformations of both hydrocarbons at 180 deg C are the previously unknown anti-Bredt hydrocarbon bicyclonona-2,7-diene (XXVIIIb) and 3-methylene-1,4-cyclooctadiene (XXV), formed in a ratio of 1 : 2.5.

Hydrogenolysis of Small Cycloalkanes, X. - Catalytic Hydrogenation of Bicycloalkanes

Dependent on n different products are obtained from bicycloalkanes by hydrogenation on Pt and Pd/C catalysts: from n = 5 onward only methylcycloalkanes of the same ring size; with n = 4 additionally 2-7 percent of cycloheptane is formed; with n = 3 ring enlargement increases to 5-20 percent and with n = 2 cyclopentane is the only product.Mainly butane is formed from bicyclobutane and no intermediate could be detected.Explanations are attempted.The expected products are produced on hydrogenation of methyl-substituted derivatives and spiroalkanes.

Process for the depyrophorization of pyrophoric metal catalysts and uses thereof

A process has been developed for the depyrophorization of pyrophoric metal catalysts, such as Raney nickel catalysts, which comprises treating said pyrophoric metal catalysts in water and/or an organic solvent with an organic nitro compound or a nitroso compound. The catalysts which are obtained according to the process of the invention are useful for carrying out all hydrogenation reaction which can be carried out using the corresponding pyrophoric catalysts. The catalysts obtained are further distinguished by high activity and extended life. They are not contaminated by contact catalyst poisons and can be used essentially without pre-activation.
