| Abstract: | Phosphono-Phosphinoformic Acid Derivatives via Alkoxycarbonylphosphono and Phosphino Acid Trimethylsilylesters The sodium salts, the chlorides and amides of the phosphono- and phosphinoformic acid esters are easily prepared under various conditions from the corresponding alkoxycarbonyl-P-trimethylsilylesters. The alkoxycarbonyl group of the synthesized compounds it not Stable in acidic solution because of an autocatalytic decarboxylation. Under these conditions the chlorides and amides are hydrolyzed too. The Structure of the compounds prepared are discussed by means of their n.m.r. data. |
