The addition of ethyl diazoacetate to olefins in the presence of a cataiytic amount of platinum complexes provides the corresponding cyclopropanes in good to excellent yields. 0 1997Published E S L Functionalized cyclopropanes provide building blocks of unprecedented synthetic potential.

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 ]
