有机磷化合物的研究 XXIV: 辛基膦酸单丁酯的合成

研究了由辛基膦酸单丁酯, 着重考察不同结构的辛基及酯丁基对皂化方法的适应性, 所报导的辛基膦酸单丁酯诺异构体均未见文献报导. 在测定化合物物化常数基础上,对它们的光谱作了研究, 对其钠盐的红外光谱特征频率也作了讨论.

Studies on organophosphorus compounds XXIV: Synthesis of monobutyl esters of octylphosphonates

A series of hitherto unknown isomeric monobutyl esters of octylphosphonates was prepared by partial saponification of di-Bu octylphosphonates either with NaOH or with ethanolamine for the quant. structure-reactivity studies. The alkaline hydrolysis was markedly accelerated by a quaternary ammonium salt-tetrabutylammonium bromide. The phase transfer catalyzed hydrolysis provides a convenient route for the preparation of mono-esters of alkylphosphonates. The completion of the reaction was successfully monitored by silicon-loaded paper chromatog. The mass spectra of the title compounds and the IR spectra of corresponding mono-sodium salts were studied and discussed.
