Synthesis of spin-labeled bispidines

Conjugates of bispidines and free radicals of the (2,2,6,6-tetramethylpiperidin-1-yl)-oxyl type were synthesized for the first time. The conjugates were obtained by the alkylation reaction of NH-bispidines with electrophilic chloro derivatives containing a free radical. The structure of the latter w...

Description
Summary:Conjugates of bispidines and free radicals of the (2,2,6,6-tetramethylpiperidin-1-yl)-oxyl type were synthesized for the first time. The conjugates were obtained by the alkylation reaction of NH-bispidines with electrophilic chloro derivatives containing a free radical. The structure of the latter was established by X-ray diffraction analysis. The products obtained were characterized by IR spectroscopy, ESR spectroscopy, and high-resolution mass spectrometry.
