Nucleophilic addition of trimethylsilyl esters of tricoordinate organophosphorus acids to various functionalized aldehydes with vinyl, aryl, and heterocyclic fragments is proposed as a convenient method for the synthesis of new 1-trimethylsiloxysubstituted alkylphosphonites and their derivatives at mild conditions. Also the new functionalizedderivatives of these phosphonites, including amino groups

A General Protocol for the Synthesis of H-α-Hydroxyphosphinates
Abstract A general synthetic procedure was developed for H-α-hydroxyphosphinates via Abramov reaction. The present work is a complementary study to those reported till now. This methodology has the advantage that it can be applied to various aliphatic and (hetero)aromatic substrates. The H-α-hydroxyphosphinates were easily purified and obtained in good to excellent yields in shorter times. A 31P NMR
摘要 通过Abramov反应,开发了用于H -α-羟基次膦酸酯的通用合成方法。目前的工作是对迄今为止报道的补充研究。该方法的优点是可以应用于各种脂族和(杂)芳族底物。的ħ -α-hydroxyphosphinates被容易地纯化和在较短的时间中获得良好到优异的产率。甲31 P NMR谱的研究表明,只要求2当量的甲硅烷基化剂。 通过Abramov反应,开发了用于H -α-羟基次膦酸酯的通用合成方法。目前的工作是对迄今为止报道的补充研究。该方法的优点是可以应用于各种脂族和(杂)芳族底物。的ħ -α-hydroxyphosphinates被容易地纯化和在较短的时间中获得良好到优异的产率。甲31 P NMR谱的研究表明,只要求2当量的甲硅烷基化剂。
