In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Nickel-catalyzed hydrogen-borrowing strategy: chemo-selective alkylation of nitriles with alcohols, published in 2020, which mentions a compound: 29046-78-4, Name is Nickel(II) chloride ethylene glycol dimethyl ether complex, Molecular C4H10Cl2NiO2, SDS of cas: 29046-78-4.
The first nickel-catalyzed hydrogen-borrowing alkylation of a series of aryl acetonitriles with a variety of aryl, heteroaryl, allylic and alkyl alcs. releasing water as the byproduct (> 33 examples, up to 90% yield) was reported.
As far as I know, this compound(29046-78-4)SDS of cas: 29046-78-4 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
