Y-Ray analysis has revealed the structure of an intermediate (366) in the oligomerization of allene by nickel complexes which contains three allene units and is assumed to be formed by the series of steps in Scheme Using rhodium dicarbonyl chloride dimer and triphenylphosphine in ethanol, an allene hexamer has been isolated for which structure (367) is proposed. 2...
