In water-containing organic solvents 2-oxo-2,3-dihydronaphthoquinone derivatives are hydrated to give the corresponding 2,2-dihydroxy-2,3-dihydronaphthoquinones. The hydration is reversible; in some cases, a keto-gem-diol equilibrium is established. The susceptibility of 2-oxo-2,3-dihydronaphthoquinone derivatives for hydration depends on the donor-acceptor properties of substituents at C(3), C(6)
在含水有机溶剂中,2-氧代-2,3-二氢萘醌衍生物水合得到相应的2,2-二羟基-2,3-二氢萘醌。水合作用是可逆的;在某些情况下,建立了酮-宝石-二醇平衡。2-oxo-2,3-dihydronaphthoquinone 衍生物对水合的敏感性取决于 C(3)、C(6) 和 C(7) 处取代基的供体-受体性质,以及羟基是否存在于C(5)和C(8),以及关于有机溶剂的碱度。
