COA of Formula: C12H8Br2. I found the field of Chemistry very interesting. Saw the article Sonogashira-Hagihara and Buchwald-Hartwig cross-coupling reactions with sydnone and sydnone imine derived catalysts published in 2020, Reprint Addresses Schmidt, A (corresponding author), Tech Univ Clausthal, Inst Organ Chem, Leibnizstr 6, D-38678 Clausthal Zellerfeld, Germany.. The CAS is 92-86-4. Through research, I have a further understanding and discovery of 4,4′-Dibromobiphenyl.
Seven different palladium complexes of sydnones and sydnone imines and a co-catalyst system consisting of lithium sydnone-4-carboxylate and Pd(PPh3)(4) catalyzed Sonogashira-Hagihara reactions between (hetero)aromatic bromides and 2-methylbut-3-yn-2-ol (52 examples, up to 100% yield). The co-catalyst system and a sydnone Pd complex were also tested in Buchwald-Hartwig reactions (9 examples, up to 100% yield). [GRAPHICS]
