a monomeric metaphosphate anion as an intermediate. The monomeric metaphosphate anions used in this reaction were generated by a photochemical C–P bond cleavage of the p-nitrobenzylphosphonate dianion. The photolysis of a 1:2 molar mixture of p-nitrobenzylphosphonic acid and 1,8-diazabicyclo[5.4.0]undec-7-ene (or 2,2,6,6-tetramethylpiperidine) in excess alcohol gave alkyl dihydrogenphosphate in fairly
烷基磷酸二氢盐通过可能涉及单体偏磷酸根阴离子作为中间体的程序制备。该反应中使用的单体偏磷酸根阴离子是通过对硝基苄基膦酸二阴离子的光化学 C-P 键断裂产生的。对硝基苄基膦酸和 1,8-二氮杂双环 [5.4.0] 十一碳-7-烯(或 2,2,6,6-四甲基哌啶)的 1:2 摩尔混合物在过量醇中的光解得到磷酸二氢烷基酯良好的产量。
