A convenient method for the one-step synthesis of symmetrical diaryl sulfones from aryl halides has been developed. A keystone of the method is the use of K2S2O5, which can be easily and safely handled, as a sulfur dioxide surrogate. The palladium catalyst bearing P(t-Bu)3 as a ligand enables formation of the desired sulfones without significant formation of byproducts.

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.
