The 'Inverse Electron-demand' Diels-Ader Reaction in Polymer Synthesis. Part 1. A Convenient Synthetic Route to Diethynyl Aromatic Compounds

The simple procedure whereby acetophenone derivatives are converted, by reaction with phosphoryl chloride and N,N-dimethylformamide, into β-chlorocinnamaldehydes, and thence, by base-induced elimination, into ethynylarenes, has been extended to diketones of the type MeCOC6H4COMe (m- and p-) and (p-MeCOC6H4)2X (X = O, S, SO2, CH2, CO, or a single bond): the corresponding diethynyl compounds are obtained by this route in acceptable yield. 1,3,5-Triacetylbenzene is similarly converted into 1,3,5-triethynylbenzene.

Facile Synthesis of Ethynylated Benzoic Acid Derivatives and Aromatic Compounds via Ethynyltrimethylsilane

The coupling reaction between an aromatic halide and ethynyltrimethylsilane under the catalysis of palladium(0) generated in situ, followed by treatment of the (trimethylsilyl)ethynyl product with potassium carbonate in methanol at ambient temperatures, provides a simple approach to various ethynylated benzoic acid derivatives and other aromatic compounds.The conditions for the removal of the trimethylsilyl group were very mild, so that base-sensitive functionalities on the aromatic moiety could be tolerated.
