Polarographic reduction of 4-aryl-2-(1,2-diphenyl-2-oxoethylidenehydrazino)-4-oxo-2-butenoic acids in 2-propanol-water solutions proceeds with the formation of two or three irreversible cathode waves and leads to 4-aryl-2-(1,2-diphenyl-2-hydroxyethylhydrazino)-4-hydroxybutanoic acids. The latter suffer hydrolysis with the rupture of the C2-NH bond and the formation of 4-aryl-2,4-dihydroxybutanoic acids
极谱还原2-丙醇水溶液中的4-芳基-2-(1,2-二苯基-2-氧亚乙基肼基肼基)-4-氧代-2-丁烯酸的极谱还原反应会形成两个或三个不可逆的阴极波,并导致4-芳基-2-(1,2-二苯基-2-羟基乙基肼基)-4-羟基丁酸。后者由于C 2 -NH键的断裂和4-芳基-2,4-二羟基丁酸的形成而水解。
