    “…Their characterisation revealed a structure similar to nickel formate, and hence the Eco-Ni(HCOO)(2) catalysts were tested in Suzuki–Miyaura reactions. Several aryl iodides were successfully cross-coupled to phenylboronic acids using Eco-Ni(HCOO)(2) without any ligand, a mild and green base in a mixture of green solvents.…”
