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.
