The Amide Group as Modulator of Crystalline and Liquid Crystalline Structures in Isocyano-alkylanilide Silver (I) Complexes [PDF]

open access: yes, 2015
Producción CientíficaSilver(I) complexes [AgX(CNR] and [Ag(CNR)2]X (X = anionic ligand), containing an amide-functionalized isocyanide, CNR = CN-C6H4-NHCOR, have been synthesized and their X-ray structures have been determined for [Ag(X)(CN-C6H4-NHCOCH3)]

Amide-Stabilized Enols in the Enol-Ugi Reaction: A Five-Component Synthesis of Triamides

open access: yesChemistry Proceedings, 2021
In continuation with our research in the use of enols in multicomponent reactions with isocyanides (IMCR), for the first time we have used amide-stabilized enols as the acid component in enol-Ugi reactions.

Controlling Near‐Infrared Fluorescence‐to‐Phosphorescence Ratios and Triplet Lifetimes in Rhodium(I) Dimers via Primary and Secondary Coordination Sphere Effects

open access: yesAngewandte Chemie, EarlyView.
RhI dimers with bridging aryl isocyanide and di‐phosphine ligands show NIR‐I or NIR‐II fluorescence/phosphorescence, depending on the ligands and conformational rigidity at the Rh2 core. Rh‐Rh interactions can be tuned by peripheral modification of the aryl isocyanide ligand, resulting in a rigid Rh2 core and improved photophysical properties ...

Self‐Limiting Polymerization‐Induced Crystallization‐Driven Self‐Assembly (SL‐PI‐CDSA) Enables Templated Synthesis of Chiral Plasmonic, Hybrid 2D Hexagonal Assemblies

open access: yesAngewandte Chemie, EarlyView.
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,

Reactivity of the dinuclear fulvalene cyclopentadienyl zirconium cationic species \ud [{Zr(η5-C5H5)}2(μ-CH2)(μ-Cl)(μ-η5-C5H4-η5-C5H4)]+ with isocyanides and carbon monoxide: insertion reactions, spectroscopic characterization and synthetic aspects [PDF]

open access: yes, 2001
The dinuclear cationic zirconium compound [{Zr(η5-C5H5)}2(μ-CH2)(μ-Cl)(μ-η5-C5H4-η5-C5H4)][BMe(C6F5)3] 1 reacts in dichloromethane at −78 °C with three equivalents of RNC (R=tBu, 2,6-Me2C6H3) via insertion into the Zr-μ-methylene bond to give the new ...

Medicinal Chemistry of Isocyanides [PDF]

open access: yesChemical Reviews, 2021
In eons of evolution, isocyanides carved out a niche in the ecological systems probably thanks to their metal coordinating properties. In 1859 the first isocyanide was synthesized by humans and in 1950 the first natural isocyanide was discovered. Now, at the beginning of XXI century, hundreds of isocyanides have been isolated both in prokaryotes and ...

Isocyanide insertion into Au-H bonds: first gold iminoformyl complexes [PDF]

open access: yes, 2018
Isocyanides insert into gold(III)-hydrogen bonds to give the first examples of gold iminoformyl complexes. The reaction is initiated by catalytic amounts of radicals; DFT calculations indicate that this is an equilibrium reaction driven forward by ...

Selectivity in multiple multicomponent reactions: types and synthetic applications

open access: yesBeilstein Journal of Organic Chemistry, 2019
Multiple multicomponent reactions reach an unparalleled level of connectivity, leading to highly complex adducts. Usually, only one type of transformation involving the same set of reactants takes place.
