This review discusses the progress in the synthesis of poly(aryleneethynylene)s (PAEs). It covers the literature from 1999 through 2003. The last comprehensive review of PAE synthesis appeared in 2000. The present review comprehensively updates the developments in the synthesis of PAEs. Synthetic methods are discussed first, followed by the description of PAEs with novel structures and topologies...
High yield dimerization of propynylated benzenes and propynylnaphthalene by a mixture of Mo(CO) 6 and 4-chlorophenol at 140 o C in 1,2-dichlorobenzene is reported to give the corresponding disubstituted alkynes. The scope and limitation of the reaction and the influence of substitution pattern and substitution type are discussed. Oxygen or nitrogen carrying substrates metathesize...
