Ligand and metal-centred reactivity in 2,6-bis(imino)-1,4-dihydropyridinate Zn(ii) alkyls: the dual behaviour of an intriguing type of complex
(Royal Society of Chemistry, 2023)
Dihydropyridines, either free or metal-coordinated, are organic hydride transfer reductants that perform on the same premises as the natural redox cofactor NAD(P)+/NAD(P)H. 1-Bn and 1-Me are alkylzinc complexes containing ...
