A unique, covalently constructed capsular catalyst obtained by reaction of [Ni(η 5 ‐C 5 H 5 )(1,5‐cyclooctadiene)] BF 4 with the double‐calixarene‐derived diphosphine 1,3‐bis(5‐diphenylphosphino‐25,26,27,28‐tetrapropoxycalix[4]aren‐17‐yl)benzene ( 1 ) has been shown to polymerise butadiene at a rate considerably superior to that of previously known catalysts. The reported results indicate that the container structure of the covalent complex is retained during catalysis.
