NITROXIDE RADICAL,ITS PRODUCTION PROCESS AND ITS USE IN MAGNETOMETRY

A nitroxide radical of the formula (I) or (II): (I) (II) in which R1 and R2 are independently chosen from among the optionally deuterated alkyl, alkoxyl, dialkylaminyl and phenyl radicals, H, D or Cl; R3, R8 and R9 are independently chosen from among the optionally deuterated alkyl, alkoxyl and phen...

Zusammenfassung:A nitroxide radical of the formula (I) or (II): (I) (II) in which R1 and R2 are independently chosen from among the optionally deuterated alkyl, alkoxyl, dialkylaminyl and phenyl radicals, H, D or Cl; R3, R8 and R9 are independently chosen from among the optionally deuterated alkyl, alkoxyl and phenyl radicals; R4, R5, R6 and R7 are independently chosen from among the optionally deuterated alkyl, alkoxyl, dialkylaminyl and phenyl radicals, COOH, OH, OD, H, D, a halogen, COOR (in which R is an alkyl radical); R10 and R11 are independently chosen from among optionally deuterated alkyl, alkoxyl, dialkylaminyl and phenyl radicals, COOH, OH, OD, H, D, a halogen, COOR (in which R is an alkyl radical) or represent an oxygen atom linked with the cycle of the radical by a double bond is described.
