Synthesis of 2,2,5,5-tetramethyl-3-imidazoline-1-oxyl
摘要:
Condensation of alpha-(hydroxylamino)-2-methylpropanal with acetone an ammonia afforded 2,2,5,5-tetramethyl-3-imidazoline-1-oxyl, the first member of a series of stable nitroxyl radicals which are derivatives of 3-imidazoline. It was shown that 2,2,5,5-tetramethyl-2,5-dihydropyrazine-1,4-dioxide can reversibly add two molecules of water or ammonia to the nitrone groups.
