CpRu-Catalyzed O-H Insertion and Condensation Reactions of α-Diazocarbonyl Compounds

[CpRu(CH3CN)(3)][PF6] and dilmine ligands catalyze together the decomposition of alpha-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.
