Urea Synthesis from Isocyanides and O-Benzoyl Hydroxylamines Catalyzed by a Copper Salt
Molecules, 2022 In the presence of CuOAc, a series of unsymmetric ureas can be generated in moderate to good yields under mild reaction conditions (10 mol% of CuOAc, 2 equiv t-BuONa or PhONa, 30 °C), using aryl isocyanides and O-benzoyl hydroxylamines as the readily ...

The Nef Reaction of Isocyanides
, 2014 International audienceThe interaction of isocyanides with acyl chlorides was first reported by Nef in 1892. The resulting α-keto imidoyl chlorides may be hydrolyzed to form α-keto amides.

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.This work details the rapid generation (t ≤ 5 min) of size‐tunable, ultralow dispersity (Ð ≤ 1.01) 2D hexagonal nanosheets by self‐limiting polymerization‐induced crystallization‐driven self‐assembly (SL‐PI‐CDSA) of modular and templating poly(aryl isocyanide) block copolymers, with functions that permit post‐polymerization modifications. Specifically,

Synthesis of N-7-Substituted Purines from Imidazole Precursors
Molecules, 1999 Synthesis of purines and purine mono-1-oxides from the respective 5-substituted 4-nitroimidazole derivatives is described. The commercially available 4-nitroimidazole, in a few simple steps (including Vicarious Nucleophilic Substitution of Hydrogen), was

The Chemistry of Phenylimidotechnetium(V) Complexes with Isocyanides: Steric and Electronic Factors
Molecules, 2022 Organometallic approaches are of ongoing interest for the development of novel functional 99mTc radiopharmaceuticals, while the basic organotechnetium chemistry seems frequently to be little explored. Thus, structural and reactivity studies with the long-

Structure and Reactivity of Glycosyl Isocyanides
European Journal of Organic Chemistry, 2018 3D structural information was obtained from mono‐, di‐ and trisaccharide formamide and isocyanide derivatives by analysis of their X‐ray crystal structure and NMR spectroscopy. The isocyanide anomeric effect was observed. Data mining of the Cambridge Structural Database (CSD) was performed and statistically confirmed our findings.
