Tris[bis(triphenylphosphoranylidene)ammonium] pyrophosphate (PPN pyrophosphate) was used in the SN2 displacements of the tosylate ion from 5'-tosylnucleosides to afford nucleoside-5'-diphosphates. Selective precipitation permitted the direct isolation of nucleoside-5'-diphosphates from crude reaction mixtures.
焦磷酸三[双(三苯基磷亚基)铵](PPN焦磷酸盐)用于使对甲苯磺酸根离子从5'-对甲苯磺酰核苷中发生SN2取代反应,以得到核苷-5'-二磷酸。选择性沉淀使得能够从粗反应混合物中直接分离出核苷-5'-二磷酸。
