The reaction of dialkylphosphinous chlorides (1) with arylmagnesium bromides carried out in the air atmosphere was found to afford aryl-dialkylphosphine oxides (2) and aryl dialkylphosphinates (3) in a comparable quantity. Formation of the latter product (3) is the first example that an aryl-dialkylphosphine, formed as an intermediate, is autooxidized to the corresponding phosphinate. © 2001 John Wiley
发现二烷基氯化亚膦(1)与芳基溴化镁的反应在空气气氛中进行,得到相当数量的芳基-二烷基氧化膦(2)和芳基二烷基次膦酸酯(3)。后一产物(3)的形成是作为中间体形成的芳基-二烷基膦被自氧化成相应次膦酸盐的第一个例子。© 2001 John Wiley & Sons, Inc. 杂原子化学 12:38–41, 2001
