The polymeric complex [Ru2(CO)4(μ-OAc)2](n) is the first Ru(I) catalyst that efficiently catalyzes cyclopropanation of alkenes with diazoacetic esters. The related dinuclear catalyst Ru2(CO)4(μ-OAc)2(MeCN)2 shows a similar performance only for cyclopropanation of monosubstituted alkenes.
Novel process for the preparation of tetra-substituted cyclopropane compounds

, (2008/06/13)
A process for the preparation of tetrasubstituted cyclopropane compounds of the formula STR1 wherein Y is selected from the group consisting of --CN and --COOR, R is selected from the group consisting of hydrogen and alkyl of 1 to 6 carbon atoms and R1, R2, R3 and R4 are individually selected from alkyl of 1 to 4 carbon atoms or R1 and R2 or R3 and R4 together with the carbon atoms to which they are attached form a carbon homocycle of 3 to 6 carbon atoms with the 2 substituents not forming the ring being alkyl of 1 to 4 carbon atoms or R1 and R2 on the one hand and R3 and R4 on the other together with the carbon atom to which they are attached form a carbon homocycle of 3 to 6 carbon atoms which are useful intermediates for the preparation of insecticidal esters and novel intermediates.
