A new rhodium porphyrin catalyzed regioselective transfer hydrogenolysis of both activated and unactivated cyclopropanes employing iPrOH as the hydrogen source was discovered. The reaction mechanism for the C-C σ-bond activation of cyclopropanes was identified through an initial radical substitution with rhodium(II) metalloporphyrin radical to give a rhodium porphyrin alkyl, followed by hydrogenolysis with iPrOH to give the corresponding acyclic alkanes and regenerate rhodium(II) metalloporphyrin radical.

Without diazo: The reductive coupling of olefins with dichloro compounds in the presence of a ruthenium catalyst and magnesium gives cyclopropanes in good yield (see scheme).
Steric Retard of Internal Rotation in 1-Carbomethoxy-1,2-diphenylcyclopropane
Doering, W. von E.,Robertson, L. R.,Ewing, E. E.

The high preference (RA = 13) found by Chmurny and Cram for internal rotation of the hydrogen-phenyl carbon bond over the carbomethoxy-phenyl carbon bond in 1-carbomethoxy-1,2-diphenylcyclopropane appears to originate in a steric effect.There b
