Abstract

Wynalazek dotyczy 3,3',5,5'-tatra(dihydroksyfosforylo)bifelylu o wzorze 1 oraz sposób wytwarzania 3,3',5,5'-tatra(dihydroksyfosforylo)bifelylu o wzorze 1, który polega na tym, że do otrzymanego znaną metodą 3,3',5,5'-tetrabromobifenylu dodaje się fosforyn diizopropylowy w stosunku molowym 4,8:1 względem 3,3',5,5'-tetrabromobifenylu, diizopropyloetyloaminę w stosunku molowym 5,2:1 względem 3,3',5,5'-tetrabromobifenylu oraz katalizator palladowy i toluen jako rozpuszczalnik i otrzymuje się 3,3',5,5'-tetrakis(diizopropyloksyfosforylo)bifenyl, po czym w wyniku hydrolizy kwasowej za pomocą stężonego kwasu solnego otrzymuje się 3,3',5,5'-tetra(dihydroksyfosforylo)bifenyl.The invention relates to 3,3 ', 5,5'-tatra (dihydroxyphosphoryl) bifelyl of formula 1 and a process for producing 3,3', 5,5'-tatra (dihydroxyphosphoryl) bifelyl of formula 1, which consists in by the known 3,3 ', 5,5'-tetrabromobiphenyl method, diisopropyl phosphite is added in a molar ratio of 4.8: 1 relative to 3.3', 5.5'-tetrabromobiphenyl, diisopropylethylamine in a molar ratio of 5.2: 1 relative to 3, 3 ', 5,5'-tetrabromobiphenyl and a palladium catalyst and toluene as a solvent to obtain 3,3', 5,5'-tetrakis (diisopropyloxyphosphoryl) biphenyl, followed by acid hydrolysis with concentrated hydrochloric acid to give 3, 3 ', 5,5'-tetra (dihydroxyphosphoryl) biphenyl.
