Phosphorylation of N-alky lated imidazoles and benzimidazoles at C-2 by CH3POCl2, PhPOCl2-POCl3 in pyridine-triethylamine solution is described. The formed heteroaryl-substituted phosphinic or phosphonic acid chlorides were transformed without isolation into the corresponding phosphinic (phosphonic) acids, their salts or amides with moderate yields This reaction opens a simple way to potential haptens derived from
CH 3 POCl 2,PhPOCl 2 -POCl 3使N-烷基化的咪唑和苯并咪唑在C-2处磷酸化描述了在吡啶-三乙胺溶液中的溶液。形成的杂芳基取代的次膦酸或膦酰氯无需分离即可转化为相应的次膦酸(膦酸),其盐或酰胺,收率适中。该反应为衍生自次膦酸的潜在半抗原开辟了一条简单的途径。许多反应,可用于获得催化抗体。用作半抗原前体的官能化杂芳基取代的次膦酸是通过1-烷基-5-硝基苯并咪唑的磷酸化或使用新的磷酸化试剂-(4-三氯甲基苯基)膦酸二氯丁酮获得的。
