Popis:	Oxidation of the triple bond in 4-alkynylpyrazoles 2a – e and acetylenic derivatives of the crown-ethers 7a , b with PdCl 2 –DMSO has been carried out to give unsymmetrical hetaryl-1,2-diketones 3a – e ; 8a , b . Attempts to oxidize the triple bond in 5-alkynylpyrazole 6 and alkynylpyridines 5a , b and 9 failed.
