Article abstract of DOI:10.1007/BF01169716

A novel carborane-containing compound with ethynyl groups, 1.2-bis<4-(4'-ethynylphenoxy)phenyl>-o-carborane, was synthesized.Cross-linking with 4-iodo- and 4,4'-diiododiphenyl ethers catalyzed by Pd complexes afforded the model bis-arylene ethynylenes and
