In the presence of Cu(acac)2(Hacac = acetylacetone) someαω-bis-diazoketones couple intramolecularly with loss of nitrogen giving cycloalk-2-ene-1,4-diones; the enediones can be converted into fused ring cyclopentenones by successive treatment with sodium dithionite and sodium hydroxide.

Derivatives of macrocyclic crown ethers in which two ethereal oxygen atoms have been replaced by carbonyl groups have been synthesised by the bis-(acetylacetonato) copper-catalysed cyclisation of αω-bis-diazo-ketones with polyethyleneglycols; three such oxo-crownethers complex with potassium ion in chloroform.
