The crystal structures of seven α‐aryl‐α‐hydroxyphosphonates synthesized by the Pudovik reaction of substituted benzaldehydes and dialkyl phosphites, namely dimethyl [(hydroxy)(phenyl)methyl]phosphonate, C9H13O4P, dimethyl [(3,4‐dimethoxyphenyl)(hydroxy)methyl]phosphonate, C11H17O6P, dimethyl (1‐hydroxy‐1‐phenylethyl)phosphonate, C10H15O4P, dimethyl [1‐hydroxy‐1‐(4‐nitrophenyl)ethyl]phosphonate, C10H14NO6P
由取代的苯甲醛和亚磷酸二烷基酯的Pudovik反应合成的七种α-芳基-α-羟基膦酸酯的晶体结构,即[(羟基)(苯基)甲基]膦酸二甲酯,C 9 H 13 O 4 P,二甲基[(3, 4-二甲氧基苯基)(羟基)甲基]膦酸酯,C 11 H 17 O 6 P,二甲基(1-羟基-1-苯基乙基)膦酸酯,C 10 H 15 O 4 P,二甲基[1-羟基-1-(4-硝基苯基]乙基]膦酸酯,C 10 H 14 NO 6 P,二苄基[羟基(2-硝基苯基)甲基]膦酸酯,C 21 H 20 NO研究了6 P,[(3-氯苯基)(羟基)甲基]膦酸二苄酯C 21 H 20 ClO 4 P和[羟基(4-甲基苯基)甲基]膦酸二苄酯C 22 H 23 O 4 P更好地了解这类固态分子的组织。从这一系列化合物获得的晶体显示出在C-OH…O = P链状堆积和具有这种功能的分子间对的氢键桥的二聚体类型之间达到平衡。该描述基于主要的
