Application

Application Guide for Palladium Catalyzed Cross-Coupling Reactions
Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) is used as a catalyst:

  • In the enantioselective construction of indole-fused bicyclo[3.2.1]-octanes via an aminopalladition-triggered Heck-type reaction.
  • In the synthesis of phenanthridine derivatives from ortho bromo N-tosylhydrazones and 2-aminophenylboronic ester via Suzuki cross-coupling reaction followed by intramolecular condensation reaction.
  • In the synthesis of indenones by Pd-catalyzed annulation of an ortho-halobenzyl alcohol with internal alkynes.
