웹A green Barluenga–Valdés cross-coupling reaction for the synthesis of 1,1-diarylethylenes using palladium catalysis has been developed. The new catalytic system based on Pd/Xphos–SO3Na or Pd/MeDavephos–CF3SO3 in PEG/H2O under microwave irradiation was found to be the best conditions for this transformation. The recyclability of the palladium … 웹2024년 3월 14일 · Infobox references. Bis (pyridine)iodonium (I) tetrafluoroborate or Barluenga's reagent, named after José Barluenga, [1] is a mild iodinating reagent. Commercially available, it may be prepared by reacting iodine with pyridine in the presence of silver tetrafluoroborate supported on silica gel.
