The simple synthetic procedure for preparation of α-aryl-α-diazophosphonates via a diazo transfer reaction is proposed. Benzylphosphonates reacted with tosyl azide (TsN3) in the presence of potassium tert-butoxide (KOtBu) to afford diazophosphonates in a yield up to 79%. The proposed method is general. The reaction uses easily available starting materials, tolerates various functional groups, and may
提出了通过重氮转移反应制备α-芳基-α-重氮膦酸盐的简单合成方法。在叔丁醇钾 (KO t Bu)的存在下,膦酸苄酯与叠氮化甲苯磺酰 (TsN 3 ) 反应得到重氮膦酸酯,产率高达 79%。建议的方法是通用的。该反应使用容易获得的起始材料,耐受各种官能团,可用于数克规模的合成。
