Substituted 2-aryl-propionaldehydes tautomerize in dimethyl sulfoxide to the corresponding enoles. The ratio of the tautomers can be described by Hammett σ-values, as in the case of imin-enamine-tautomeric 2-aryl-propionaldehyde methylimines. This is the first example of a linear free energy relationship between the two forms of tautomerism.
取代的2-芳基-丙醛在二甲基亚砜中互变异构成相应的烯醇。如在亚胺-烯胺-互变异构体2-芳基-丙醛甲基亚胺的情况下,互变异构体的比率可以由哈米特σ值描述。这是互变异构的两种形式之间线性自由能关系的第一个例子。
