The catalyst was applied for Ulmann reaction using s series of aryl halide and phenol derivatives in DMSO and preparation of biaryls via Suzuki C-C reactions between aryl halides and phenyl boronic acid. The Catalyst was characterized by FT-IR, XRD, SEM, ICP-AES and TGA techniques. The catalyst demonstrated high reaction efficiency with more than 90% reaction yield. The catalyst indicated good performance after several times recovery and reuse. %U https://www.echemcom.com/article_96646_a9f740405f4c554893ba73e76b45db25.pdf
