Bromotrimethylsilane is highly selective for P–O silyldealkylation of mixed carboxylate–phosphonate alkyl esters and can be used to prepare trimethylsilyl amido-, alkynyl-, and iodoalkyl-phosphonates in good yield, thus making the corresponding phosphonic acids readily available via hydrolysis with neutral H2O.
溴代三甲基硅烷对混合的羧酸酯-膦酸酯烷基酯的P-O甲硅烷基脱烷基化反应具有高度选择性,可用于制备三甲基硅烷基酰胺基,炔基和碘代烷基膦酸酯,收率很高,因此使相应的膦酸易于通过中性H水解获得2 O.
