The synthesis of a variety of new halo-F-methylphosphonates has been achieved by a Michaelis–Arbuzov type reaction between a halo-F-methane and a trialkyl phosphite. This synthesis has proved to be of wide scope and utility for the high yield preparation of a number of heretofore unknown compounds. The 1H, 19F, 13C and 31P NMR spectroscopic properties are reported in detail. The mechanism for the formation
卤代F-甲烷与亚磷酸三烷基酯之间的Michaelis-Arbuzov型反应已实现了多种新的卤代F-甲基膦酸酯的合成。已证明该合成对于高产率制备许多迄今未知的化合物具有广泛的范围和实用性。的1 H,19男,13 C和31种P NMR光谱性质报告于细节。溴二氟甲基膦酸酯的形成机理已证明是通过二氟卡宾:CF 2的中间体来进行的。已显示膦酸酯产物与多种试剂反应。氟化物和醇盐离子通过攻击在磷反应与碳-磷键的裂解和形成[:CF 2 ]从bromodifluoromethylphosphonates和CFBR 2 -从dibromofluoromethylphosphonates阴离子。碘离子和叔膦通过攻击酯碳反应生成稳定的膦酸酯盐。用50%的HCl水溶液水解膦酸酯,得到预期的膦酸。三甲基甲硅烷基溴化物侵蚀磷酰基氧,得到双(三甲基甲硅烷基)酯。
