was also made for n-propyl isocyanide, which was suspected, because of its color, to be contaminated with a small amount of n-propyl iodide. The values of the equilibrium constants were averaged, with the concentration of free isocyanide as a weight factor. The equilibrium constants obtained in this way are 2.0 X 105 for ethyl isocyanide, 1.1 X 105 for n-propyl isocyanide, 1.4 X 104 for isoprop...

The adsorption of methyl isocyanide (CH3NC) and acetonitrile (CH3CN) has been studied on Pd(111). Methyl isocyanide adsorbs on Pd(111) at 80 K at low coverages with the isocyanide functionality oriented close to parallel to the surface; the surface-bound species reorients to a geometry in which the isocyanide group is perpendicular to the surface as the coverage increases. Desorbing the excess ...

Isocyanide is a potential antifouling compound in marine environments. In this study, we investigated its mode of action in three aquatic organisms. Two of them, the bryozoan Bugula neritina and the barnacle Balanus amphitrite, are major marine fouling invertebrates, and the other organism is the non-target species zebrafish Danio rerio. In the swimming larvae of B. neritina, isocyanide did not...

Cyclometalated iridium complexes with efficient phosphorescence and good electrochemical stability are important candidates for optoelectronic devices. Isocyanide ligands are strong-field ligands: when attached to transition metals, they impart larger HOMO-LUMO energy gaps, engender higher oxidative stability at the metal center, and support rugged organometallic complexes. Aryl isocyanides off...

In this work we report a study on the effect of systematic ancillary ligand modifications on electrochemical and photophysical properties of cationic biscyclometalated bis(arylisocyanide)iridium(iii) complexes. Nine new Ir(iii) complexes were synthesized using three different cyclometalating (C^N) ligands (2,4-difluorophenylpyridine (F2ppy), 2-benzothienylpyridine (btp), and 2-phenylbenzothiazo...

p-Toluenesulfonylmethyl isocyanide (TosMIC) is used as the isonitrile component in Passerini reactions with chromone-3-carboxaldehydes to yield chromenyl-amidoesters in good yields.

The present work provides a comprehensive theoretical and experimental study of the vibrational circular dichroism of (S)-α-phenylethyl isocyanide in chloroform. The structure in solution is investigated systematically by density functional theory calculations starting from the isolated molecule and then by considering solvent effects implicitly using the PCM and explicitly by taking into accou...

The cycloaddition of the von Leusen's reagent (p-tolylsulfonyl)methyl isocyanide (TosMIC) to alpha-aroylketene dithioacetals (AKDTAs) in the presence of sodium hydride in THF at rt resulted in a facile synthesis of the 4-aroyl-3-methylsulfanyl-2-tosylpyrroles 3 in good yield along with a minor amount of 4-[(4-methylphenyl)sulfonyl]-1-[(methylsulfanyl)methyl]-1H-imidazole 4. This study lead to t...

The synthesis and anti-cancer activity evaluation of fused imidazoquinoline compounds is reported in this paper. Yb(OTf)3 has been utilized as a catalyst for the synthesis of 1,4-diaryl substituted imidazo[4,5-c]quinolines via a modified Pictet-Spengler approach. The desired imidazole ring was synthesized from imines using TosMIC (toluenesulfonylmethyl isocyanide) and subsequently functionalize...

Liver cytochrome P-450 forms two spectroscopically and functionally distinct compounds with ethyl isocyanide, but the structural basis for the difference between them is unknown. We have examined the relative rates of formation of the two compounds at low temperatures. Reduced cytochrome P-450 was generated photochemically from its carbon monoxide complex at temperatures below O’, and allowed t...
