A robust porous cage was synthesized using irreversible alkyne coupling reactions. Reaction with dicobaltoctacarbonyl gave exhaustive metalation of the 12 alkyne units to give the Co24(CO)72 adduct of the cage in a single pot.
Dihalodiphenylacetylenes are conveniently synthesized by a doubleelimination reaction of β-substituted sulfones which are readily obtained from halogen-substituted benzyl sulfone and benzaldehyde derivatives. Halogens can be incorporated at any desired positions in the diphenylacetylene skeleton simply by choosing the substitution position of the halogen on the aromatic rings of the starting compounds
