    Abstract: The invention comprises organo-aluminum compounds containing alkyl-substituted cyclopentyl methyl groups of the neopentyl type. The may be prepared by treating 2,5-alkyl-substituted hexadienes with a compound containing an aluminium hydrogen bond or a substance which yields such a compound in the presence of heat, said treatment being affected in an inert atmmosphere. The reaction may be represented as follows (using 2,5-dimethyl hexadiene-1,5): The reaction may be carried out as shown with aluminium hydride, o with an alkyl aluminium hydride or a trialkyl aluminium: in the latter cases on olefin is set free. Displacement reaction catalysts e.g. finely divided nickel, may be present.ALSO:Alkyl substituted cyclopentanes (e.g. 1-dimethyl-3-methyl cyclopentane, 1-dimethyl-3-ethyl cyclopentane and 1-ethyl-1,3-dimethyl cyclopentane) may be obtained by hydrolysis of organo aluminium compounds containing alkyl-substituted cyclopentyl methyl groups of the neopentyl type.
