Nucleophilic Isocyanation [PDF]

open access: yesACS Omega, 2020
Isonitriles are frequently employed as both substrates for organic transformations and ligands for organometallic chemistry. However, despite the wide application of the isonitriles, their synthesis generally depends on the traditional dehydration of N-formamide.
