Here is a downstream synthesis route of the compound 6828-35-9, SDS of cas: 6828-35-9

General procedure: Aryl iodide or bromides (5.0 mmol),paraformaldehyde (5.0 mmol), Pd(OAc)2 (0.0005 mmol) (for aryliodides) or Pd(PPh3)4 (0.05 mmol) (for aryl bromides) andCs2CO3 (7.0 mmol) were reacted in DMSO at 80 oCfor 12 h. The reaction mixture was poured into H2O, and extractedwith Et2O. The internal standard (dodecane) was added to theresulting mixture, and the conversion of aryl iodide and the yield of thehydrodehalogenated product were calculated.
