Tetrakis[(S)-(+)-[(1S)-1-(4-broMophenyl)-2,2-diphenylcyclopropanecarboxylato]dirhodiuM(II) Rh2(S-BTPCP)4

Reactions

1. Chiral catalyst used for the enantioselective formation of cyclopropanes from the reaction of aryls with styryl diazoacetates.
2. Chiral catalyst used for the asymmetric synthesis of bicyclo[1.1.0]butane rings via the rhodium-catalyzed decomposition of 2-diazo-5-arylpent-4-enoates.
3. Reaction of vinyldiazoacetates with nitrones to form 2.5-dihydroisooxazoles,
