Abstract

alpha-2,6-Difluorophenyl-N-tert-butylnitrone (F2PBN) was synthesized and evaluated. A number of alkyl adducts of F2PBN were studied by ESR/ENDOR. An additional hyperfine splitting (a triplet of doublets of doublets) is reported. The existence of two (one large, one small) F-hfsc's from the ortho-fluorine atoms in the phenyl ring of most alkyl adducts was confirmed by ENDOR spectroscopy.
