Both diastereomers of the tris-allene, cyclododeca-1,2,5,6,9,10-hexaene have been obtained using a triple cyclopropylidene-allene rearrangement. On the NMR timescale, one has D 3 symmetry, and is the smallest hydrocarbon synthesised to have this symmetry, and the second has C 2 symmetry. This paper...

Summary:Both diastereomers of the tris-allene, cyclododeca-1,2,5,6,9,10-hexaene have been obtained using a triple cyclopropylidene-allene rearrangement. On the NMR timescale, one has D 3 symmetry, and is the smallest hydrocarbon synthesised to have this symmetry, and the second has C 2 symmetry. This paper describes the synthesis of two unusual cyclic tris-allenes, one of which has D 3 symmetry on the NMR timescale.
