ChemInform Abstract: General Suzuki Coupling of Heteroaryl Bromides by Using Tri-tert-Butylphosphine as a Supporting Ligand

A general procedure for the fast Suzuki coupling of major families of heteroaryl bromides was realized by using Pd(OAc)2/PtBu3 as the catalyst. Many couplings were finished within minutes at room temperature in n-butanol. Different from previous studies, three typical heteroaryl bromides were systematically examined in couplings of various heteroaryl and aryl boronic acids.
