α-羟基膦酸酯与各种取代苯甲酸或吡啶甲酸,通过酰氯或缩合剂的作用,合成了一系列的O,O-二烷基-α-苯基-α-(取代芳基甲酸酯基)-甲基膦酸酯的衍生物.它们的合成收率为61%～84%,这些化合物的结构经过核磁(1HNMR,13CNMR和31PNMR)、红外、质谱、元素分析或高分辨质谱确证,同时化合物C1的结构在晶体结构解析上进一步得到证实.利用多级质谱分析了化合物C2,C5和C8的质谱裂解规律,解释了重排离子的形成机制.
α-hydroxy phosphonates and various substituted benzoic acids or picolinic acids, a series of O, O-dialkyl-α-phenyl-α- (substituted aryl carboxylic acids Ester) -methylphosphonate derivatives, which have yields of 61% to 84%. The structures of these compounds were confirmed by nuclear magnetic resonance (1HNMR, 13CNMR and 31P NMR), infrared, mass spectrometry, elemental analysis or high resolution mass spectrometry , While the structure of compound C1 was further confirmed by the crystal structure analysis.The mass spectra of compound C2, C5 and C8 were analyzed by multi-stage mass spectrometry, and the formation mechanism of rearranged ions was explained.
