Paragraph 0040-0076, (2019/06/27)
The invention discloses a preparation method of an organic phosphine flame retardant 1-hydroxyl phosphate. The method includes the following steps that hypophosphite and aldehyde serve as raw materials, DMF/DMSO/DMP serve as solvents, a heating reaction is carried out, filtering and alcohol washing is performed after the reaction, and 1-hydroxyl alkyl phosphate is obtained; the pH value of 1-hydroxyl alkyl phosphate is adjusted to be 2-3, and 1-hydroxyl alkyl phosphate reacts with melamine, aluminum salt and zinc salt to obtain the product. According to the method, a one-pot method is utilizedto obtain1-hydroxyl alkyl phosphate, the production process is simple, the operation is easy, and the solvent and the raw materials can be repeatedly used.

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 31 P NMR spectroscopy study has shown that only 2 equivalents of a silylating agent were required.

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 functionalized derivatives of these phosphonites, including amino groups as well as certain properties of these compounds as important precursors of new functionalized 1-hydroxyalkylorganophosphorus acids, are presented.
