摘要：
Silylation of ammonium hypophosphite (1) with hexamethyldisilasane (HMDS) followed by alkylation of the intermediate bis(trimethylsilyl)hypophosphite (2) with methylchloroacetate in the presence of HMDS gives O-trimethylsilylbis(methoxycarbonylmethyl)phosphinate (3) and O, Obis(trimethylsilyl)-methoxycarbonylmethylphosphonite (4). Methanolysis of phosphinate 3 gives bis(methoxycarbonyl-methyl)phosphinic acid (5), the hydrolysis of which leads to bis(hydroxycarbonylmethyl)phosphinic acid (6). Treatment of the acids 5 and 6 with sodium hydroxide gives trisodium salt (7). © 1991, Taylor & Francis Group, LLC. All rights reserved.
