Synthesis of Pd OACs is usually accomplished by oxidative addition to a Pd(0) complex (i.e., Pd2dba3) or a suitable organo-Pd(II) species that undergoes in situ reductive elimination, such as Pd(Cp)(allyl), Pd(COD)(CH2SiMe3)2, 19 Pd(COD)(κ 2 -CH2CMe2C6H4), or Pd( DMP DAB)(CH2SiMe3)2. approaches have been quite effective for the synthesis of various Pd OACs, but the requirement for independent synthesis for each unique OAC can still be cumbersome, particularly during reaction discovery or optimization campaigns when many variations in ancillary ligand can be necessary.
