Phenylphosphonous acid adds to the carbonyl carbon atom of a variety of aldehydes and ketones to give α-hydroxyphosphinic acids. With benzylideneacetone the acid (III) is obtained along with a neutral compound shown to be the oxaphospholen oxide (IV). In contrast, condensation of phenylphosphonous acid with benzylideneacetophenone leads to the known γ-keto-acid (VII) and the oxaphospholen oxide (VIII)
苯膦酸加到各种醛和酮的羰基碳原子上,得到α-羟基次膦酸。用亚苄基丙酮可得到酸(Ⅲ)和中性化合物,即氧杂磷酰氧化物(Ⅳ)。相反,苯基亚膦酸与亚苄基苯乙酮的缩合产生已知的γ-酮酸(VII)和氧代草酰氧化物(VIII)。双亚膦酸(XII)由乙炔二羧酸二乙酯获得,从马来酸酐中分离出两种结构尚不确定的酸。
