The copper(II) chelate catalyzed addition of compounds 2-diazo-3-oxobutyrate (3) and 3-diazo-2,4-pentanedione (5) in the presence of aldehydes and ketones in refluxing aromatic solvents proceeds smoothly with the exlusive formation of dioxole derivatives.The yield of 1:1 adducts depends strongly on the nature of the copper ligands and relative concentration of catalyst employed.Dioxoles are the only volatile materials present within a 2percent detection limit. The general character of this novel cycloaddition is illustrated with the reaction of 3 and 5 with four aldehydes and nine ketone substrates.

[CpRu(CH3CN)3][PF6] and diimine ligands catalyze together the decomposition of α-diazocarbonyl compounds leading to O-H insertion and condensation reactions. In comparison with Rh(II) and Cu(I) complexes, the CpRu catalysts produce rapid and often more selective reactions. Promising enantioselectivities are obtained in dioxole syntheses.
