Application

Chlorobis(cyclooctene)rhodium(I),dimer can be used as a catalyst:
  • To synthesize enantioenriched gem-diaryl sulfonates by asymmetric 1,4-addition of aryl boronic acids to α,β-unsaturated sulfonyl compounds.
  • In direct C-arylation of N-unprotected indoles and pyrroles.
  • In the carboxylation of arenes via C-H bond activation.
