Abstract

We demonstrate the gas-phase synthesis of prop-1-ene-1,1-diol, the hitherto unreported higher energy tautomer of propionic acid. The enol was trapped in an argon matrix and characterized by IR and UV/Vis spectroscopy in combination with density functional theory computations. Upon photolysis, the enol rearranges to propionic acid and methylketene.

摘要

我们展示了1-丙烯-1,1-二醇的气相合成，它是迄今为止未报道的丙酸的高能互变异构体。烯醇被捕获在氩气基质中，并通过红外光谱和紫外/可见光谱结合密度泛函理论计算进行表征。光解后，烯醇重排为丙酸和甲基乙烯酮。
