对映体纯的二铑(II)与邻位金属化的对位取代芳基膦的配合物已被证明在重氮乙酸乙酯对苯乙烯的环丙烷化反应中具有对映选择性和非对映选择性。顺-2-苯基环丙烷甲酸乙酯的对映选择性高达 91%，非对映选择性高达 90%。
Enantiomerically pure dirhodium(II) complexes with ortho-metalated p-substituted aryl phosphines have been shown to be enantio- and diastereoselective in the cyclopropanation of styrene by ethyl diazoacetate. Enantioselectivities up to 91% and diastereoselectivities up to 90% are observed for ethyl cis-2-phenylcyclopropanecarboxylate.
