Abstract

ENDOR spectroscopy. The kinetic ESR study shows that, while aminyls 2 gradually decompose in solution at room temperature, aminyl3 is quite persistent, even in refluxing benzene, and shows no tendencyto dimerize, even at low temperatures. These interesting properties of 3 permit us to isolate 3 as radical crystals in 28-31? 6 yield. The hyperfine splitting (hfs) constants of 2 and 3, determined by ESR and ENDOR spectroscopic ...
