The unstable enolic tautomers 3-hydroxyfuran, 2- and 3-hydroxythiophene, 3-hydroxy-pyrrole, 3-hydroxy-1-methyl-pyrrole and their benzo-derivatives have been generated in solution and the rate and equilibrium constants for their ketoization determined.
已在溶液中生成了不稳定的烯键式互变异构体3-羟基呋喃,2-和3-羟基噻吩,3-羟基吡咯,3-羟基-1-甲基吡咯及其苯并衍生物,并确定了其酮化的速率和平衡常数。
