A variety of 2-(2-methylphenyl)-2-oxoethyl acetates were prepared from aromaticketones by α-oxidation in acetic acid, using palladium acetate as catalyst and (diacetoxyiodo)benzene as oxidant. The X-ray crystal structure of 5-acetyl-2-hydroxy-4-methylphenyl acetate was determined.
以乙酸钯为催化剂,(二乙酰氧基碘)苯为氧化剂,通过在乙酸中α-氧化芳族酮制备了多种2-(2-甲基苯基)-2-氧代乙酸乙酯。确定了 5-乙酰基-2-羟基-4-甲基苯基乙酸酯的 X 射线晶体结构。

An ultraviolet radiation-curable composition is provided which comprises a polyethylenically unsaturated compound and effective photosensitizing amounts of (a) a phenacyl ester, and (b) a tertiary aliphatic amine.
is a fundamental concept in organic chemistry, which provides an alternative strategy for the synthesis of target compounds which were not easily accessible by conventional methods. Herein, a mild and efficient PhI(OAc)2-promoted umpolung acetoxylation reactions of enamides was developed for the synthesis of α-acetoxy ketones. The reaction tolerates a wide range of functional groups and affords α-acetoxy
