Preparation of 2-Azarhodacyclobutanes by Rhodium(I)-Olefin Oxidation

Preparation of 2-Azarhodacyclobutanes by Rhodium(I)-Olefin Oxidation

AmAZAing metallacycles: Azarhodacyclobutane was prepared by oxidation of RhI–olefin complex 1 (see Scheme; Ts=p‐toluenesulfonyl). Both isomers 2 a and 2 b were isolated and characterized by NMR spectroscopy and mass spectrometry; their configurations were unambiguously established by NOE experiments...
