Chemoenzymatic synthesis of carbasugars from iodobenzene

Organic & Biomolecular Chemistry, 2005
The versatile enantiopure cis-dihydrodiol metabolite 1, formed by bacterial metabolism of iodobenzene, has been used for the synthesis of the pyranose carbasugars (pseudosugars) carba-beta-D-altropyranose 2, carba-alpha-L-galactopyranose 3, carba-beta-D-idopyranose 4 and carba-beta-L-glucopyranose 5.

Formation of 2-Substituted Iodobenzenes from Iodobenzene via Benzyne and Ate Complex Intermediates

Organic Letters, 1999
The generation of benzyne from iodobenzene with lithium tetramethylpiperidide in THF at −40 °C in the presence of lithium amides and ester enolates leads to mixtures in which 2-substituted iodobenzenes are often the major products. These products are obtained by iodine transfer from iodobenzene to the intermediate 2-lithioaromatics.

Neutron-induced reactions in iodobenzene

Journal of Inorganic and Nuclear Chemistry, 1962
Abstract The organic yields of radio-iodine produced by neutron irradiation of mixtures containing iodobenzene and iodine have been investigated; they were unaffected by a slow radiolytic exchange reaction and there was little evidence that they are influenced by thermal exchange occurring in the hot zone.

Self-radiolysis of iodobenzene labelled with125I

Journal of Radioanalytical and Nuclear Chemistry Letters, 1985
The radiolysis of iodobenzene labelled with125I has been investigated at liquid nitrogen and room temperatures, in the presence and absence of oxygen. After various storage times the samples were analyzed by gas chromatography, and benzene, vinyl iodide, biphenyl, and iodobiphenyl were detected.

Proton magnetic resonance spectra and distribution of electron density in iodobenzene and iodobenzene dichloride

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1967
1. The proton magnetic resonance spectra (100 MHz) of dilute solutions of iodobenzene and iodobenzene dichloride in absolute dioxane were investigated. 2. In the iodobenzene molecule, only the ortho-protons are shielded more weakly than the protons of unsubstituted benzene, while in iodobenzene dichloride, the chemical shifts of the ...

C-I stretching vibrations in iodobenzenes

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1991
Comparison of the calculated and experimental IR and Raman spectra of a series of iodobenzenes showed that the C-I stretching vibrations for these compounds correspond to a very highly polarized Raman band at 150–270 cm−1 (ρ=0.1). The position of this band depends on the mass of the para substituent and relative position of the fluorine and iodine ...

para-Selective C–H bond functionalization of iodobenzenes

Chemical Communications, 2016
An oxidation-induced strategy forpara-C–H functionalization of iodobenzenes was demonstrated, which provides a general idea for the development of new, highly selectivepara-C–H functionalization reactions.

Iodobenzene diacetate-mediated hetero-domino transformations

Tetrahedron Letters, 2002
Abstract Treatment of a series of unsaturated diols with iodobenzene diacetate (PhI(OAc) 2 ), in various solvents gave cyclic ene-acetals by a sequential oxidative cleavage-intramolecular [4+2] cycloaddition. The reaction is easy to perform, can be scaled up safely and occurs efficiently irrespective of the diol stereochemistry.
