Ruthenium complexes of the type [RuX(Cp%)(PPh 3 ) 2 ] (X=Cl and H; Cp%=Cp, Cp\*, indenyl, and carboranyl) efficiently catalyse olefin cyclopropanation with diazoesters, and the cis/trans stereoselectivity of the resulting cyclopropanes strongly depends on the Cp% ligand. With [RuCl(Cp\*)(PAr 3 ) 2 ]
Bis(imido) chromium(VI) complexes are efficient catalysts for promoting the cyclopropanation of activated monosubstituted olefins with ethyl diazoacetate. 2,2'-Disubstituted activated olefins and non-activated ~-and cyclo-olefins, however, are much less reactive.
