| titleOfInvention | NEW DERIVATIVES OF TETRAHYDRO-1,4,5,6 TETRAZINE-1,2,4,5 ONE-3, THEIR PROCESS FOR THE PRODUCTION AND APPLICATION OF STABLE RADICALS WHICH CONSTITUTE THE DEHYDROGENATED FORM AS CONTRAST AGENTS IN NUCLEAR MAGNETIC RESONANCE |
| abstract | To prepare the radicals of formula Ib, a compound of formula II is reacted with a compound of formula III, which results in the compound of formula Ia, then the dehydrogenation of the latter is carried out. (CF DRAWING IN BOPI) R ** 1 = aryl; R ** 2 = aryl optionally substituted by at least one group having a mesomeric or inducing, electron donor or withdrawing effect; R ** 3 = aryl optionally substituted by at least one group with a mesomeric or inducing effect, an electron donor; Hal = halogen. |
