Tang, Huiling; Liu, Mengna; Zhu, Meiqi; Cui, Benqiang; Shi, Yanhui; Cao, Changsheng published an article in 2021. The article was titled 《C(sp2)-C(sp2) Suzuki cross-coupling of arylammonium salts catalyzed by a stable Pd-NHC complex》, and you may find the article in Tetrahedron.Formula: C7H9BO3 The information in the text is summarized as follows:
The authors developed the Suzuki-Miyaura cross-coupling of aryl ammonium salts via C-N bond activation catalyzed by an easily prepared and bench-stable palladium-N-heterocyclic carbene complex. The reaction proceeded well under mild conditions with phenylboronic acid and pinacol ester or anhydride and provided biaryls Ar1-Ar2 [Ar1 = 1-naphthyl, Ph, 2-pyridyl, etc., Ar2 = Ph, 4-MeC6H4, 4-PhC6H4, etc.] in up to 97% yield with good functional group compatibility. The direct arylation of arylamine could be performed by a two-step, one-pot process and a protocol could be performed on the gram scale. After reading the article, we found that the author used 3-Methoxyphenylboronic acid(cas: 10365-98-7Formula: C7H9BO3)
3-Methoxyphenylboronic acid(cas: 10365-98-7) belongs to boronic acids. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis.Formula: C7H9BO3
