Stepwise growth of oligo(p-phenylene oxide)s and cyclization via the Ullmann coupling reaction by using CuI/N,N-dimethylglycine afforded cyclic oligo(p-phenyleneoxide)s, -(C6H4O)n-(n = 6-10). The structure of the new cyclophanes was determined by X-ray crystallography, which revealed that they have planar or slightly bent structures with diameters of 1.0-1.5 nm.

, p. 572 - 574 (2007/10/03)
A series of aryl ether oligomers end-capped with ethynyl groups have been synthesised via a three-step process, i.e. iodination of oligo-aryl ethers, nucleophilic substitution of the iodide group with 2-methyl-3-butyn-2-ol catalysed by Pd/Cu and subsequen
