Kinetic and stereochemical evidence has been obtained from the dehydromethoxylation of 2-halogeno-3-methoxy-1,3-diphenylpropan-2-ones with isopropoxide in isopropyl alcohol that is consistent with an E1cB reversible mechanism. The influence of the halogen both on the deprotonation rate and upon the methoxy-group expulsion has been evaluated.
在异丙醇中,2-异丙基-3-卤代-3-甲氧基-1,3-二苯丙烷-2-酮与异丙醇的脱氢甲氧基化反应已获得动力学和立体化学证据,这与E 1cB可逆机理一致。已经评估了卤素对去质子化速率和对甲氧基排出的影响。
