Tang, Huiling; Liu, Mengna; Zhu, Meiqi; Cui, Benqiang; Shi, Yanhui; Cao, Changsheng published the artcile< C(sp2)-C(sp2) Suzuki cross-coupling of arylammonium salts catalyzed by a stable Pd-NHC complex>, SDS of cas: 190788-60-4, the main research area is phenylnaphthalene preparation; arylammonium salt phenylboronic acid Suzuki cross coupling palladium catalyst.
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.
Tetrahedron published new progress about Biaryls Role: SPN (Synthetic Preparation), PREP (Preparation). 190788-60-4 belongs to class ethers-buliding-blocks, and the molecular formula is C13H19BO3, SDS of cas: 190788-60-4.
