摘要:磷酸单酯是在三丁胺存在下由磷酸(1或2当量)和醇(1当量)的混合物合成的.该反应由亲核碱如n-烷基咪唑和4-(n,N-二烷基氨基)吡啶促进.2',3'-O-异亚丙基核糖核苷被选择性地转化为5'-单磷酸酯,而没有保护核碱基中的氨基.

摘要:A general, reproducible, and simple synthetic method that employs readily available chemicals permits control of the size, shape, and size distribution of metal oxide nanocrystals. The synthesis entails reacting a metal fatty acid salt, the corresponding fatty acid, and a hydrocarbon solvent, with the reaction product being pyrolyzed to the metal oxide. Nearly monodisperse oxide nanocrystals of Fe 3 O 4 , Cr 2 O 3 , MnO, Co 3 O 4 , NiO, ZnO, SnO 2 , and In 2 O 3 , in a large size range (3-50 nm), are described. Size and shape control of the nanocrystals is achieved by varying the reactivity and concentration of the precursors.
