Nucleophilic substitutions and radical reactions of phenylazocarboxylates

tert-Butyl phenylazocarboxylates are versatile building blocks for synthetic organic chemistry. Nucleophilic substitutions of the benzene ring proceed with aromatic amines and alcohols under mild conditions. The attack of aliphatic amines may be directed to the aromatic core as well as to the carbonyl unit leading to azocarboxamides. The benzene ring can further be modified through radical reactions, in which the tert-butyloxycarbonylazo group enables the generation of aryl radicals at either elevated temperatures or under acidic conditions. Radical reactions include oxygenation, halogenation, carbohalogenation, carbohydroxylation, and aryl-aryl coupling.

4-substituted tert-butyl phenylazocarboxylates-synthetic equivalents for the para-phenyl radical cation

First electrophile, then radical: 4-Substituted tert-butyl phenylazocarboxylates 1 are versatile synthetic equivalents of the para-phenyl radical cation 2. The tert-butyloxycarbonylazo group enables nucleophilic substitutions to proceed under mild conditions and can later be employed for the generation of aryl radicals. Copyright

INDICYANINE DYES AND THE DERIVATIVES THEREOF FOR ANALYSING BIOLOGICAL MICROMOLECULES

The invention relates to two series of synthesised indolenine pentamethine dyes (37 compounds) comprising a reactive group in the third and fifth positions of the indolenine cycle, respectively. A method for producing, extracting and purifying the dyes and the precursors thereof, consisting in determining the absorption and fluorescence maxima, molecular extinction factors, fluorescence quantum yields, relative fluorescence effectiveness at excitation on a wavelength of 635 nm (detection of 670 nm) and 655 nm (detection of 690 nm), relative light stability and comparative sensitivity of detection of marked oligonucleotides on biochips of the claimed dyes, is disclosed. The use of the claimed dyes in the form of fluorescent marks for oligonucleotide and protein chips is also disclosed.

ARYL RADICALS BY COPPER(II) OXIDATION OF HYDRAZINES: A NEW METHOD FOR THE OXIDATIVE AND REDUCTIVE ARYLATION OF ALKENES

A new source of aryl radicals interesting from the preparative point of view has been found in the reaction of arylhydrazines and copper(II) sulfate.The process allows selectively both the reductive and oxidative arylation of alkenes.

Direct Conversion of Arylamines to the Halides by Deamination with Thionitrite or Related Compounds and Anhydrous Copper(II) Halides

Reactions of various arylamines with either t-butyl thionitrite, t-butyl thionitrate, or p-toluenesulfonyl nitrite in the presence of anhydrous copper(II) halides under mild conditions gave corresponding aryl halides in good yields.This reaction in the presence of such olefins as acrylonitrile, styrene, and acrylic acid gave the corresponding 2-aryl-1-haloethanes as the main products. t-Butyl thionitrite, t-butyl thionitrate, and p-toluenesulfonyl nitrite were found to be better deaminative reagents than alkyl nitrites or alkyl nitrates due to their weak sulfur-nitrogen bonds.
