Amination of Aryl Boronic Acids with Alkylnitrites: A Convenient Complement to Cu-Promoted Reductive Amination

Copper-catalyzed amination of aryl boronic acids with alkylnitrites leading to symmetrical diarylamines with a practical 50-80% yield was elaborated. Two C(sp2)-N bonds are formed in the one-pot process under mild conditions. This new approach to diarylamines is a complement to the Cu-assisted reductive amination of aryl boronic acids avoiding preliminary synthesis of nitrosoarenes. The possible reaction scheme based on quantum chemical calculations was suggested, clarifying key intermediates.

VARIABLE TEMPERATURE ESR SPECTRA OF 1-(3,4,5-TRIMETHOXY-BENZOYL)-2,2-BIS(3,5-DI-TERT-BUTYL-PHENYL)HYDRAZYL AND ITS 1-(15)N-CONGENER

The title free radicals were obtained by oxidation of the corresponding hydrazines which were synthesized and characterized by elemental analysis, IR and 1H-NMR spectra. The ESR spectra of the free radicals were recorded in toluene in the temperature range -50 deg C to +90 deg C. The simulated ESR spectra indicate a higher spin density at the tricoordinated N-2 nitrogen of the diarylamino group (hfc aN = 0.862 mT) than at the dicoordinated N-1 nitrogen atom (hfc aN = 0.830 mT). In the temperature range 0 deg C to 30 deg C the activation free energy for interconversion of conformers was determined to be ΔG(excit.) = 7.80 kcal/mol.

Factors Affecting the Stability and Equilibria of Free Radicals. 14. Unexpected Spin Densities in 1-(Trifluoroacetyl)-2,2-diarylhydrazyl Revealed by 15N Labeling

1-(Trifluoroacetyl)-2,2-bis(3,5-di-tert-butylphenyl)hydrazyl and its congener labeled at the dicoordinated 1-nitrogen atom with 15N were prepared.ESR spectra of solutions of both compounds were recorded and hyperfine coupling constants determined by optimizing simulated spectra.Unlike all other 1,2,2-triarylhydrazyls which have been investigated, the hyperfine coupling constant for the dicoordinated nitrogen is lower (0.7 mT) than that for the tricoordinated nitrogen (1.0 mT) in this free radical.This striking result raises questions about the mode of trifluoroacetyl group participation in ? electron delocalization.
