Pruschinski, Lucas published the artcileSuzuki-Miyaura Cross-Couplings under Acidic Conditions, Application of 2,5-Dibromo-3,4-dinitrothiophene, the publication is Synthesis (2020), 52(6), 882-892, database is CAplus.
Suzuki-Miyaura reactions with Pd(PPh3)4 had carried out using lithium N-phenylsydnone-4-carboxylate as additive, which gave best yields at pH 5.7 in a mixture of acetic acid, water, and sodium carbonate. Reaction parameters such as the Pd source, the solvent, reaction time and temperature, acid, base and carboxylate have been varied and some representative examples of the Suzuki-Miyaura reaction have been examined
