一般描述
多磷酸(PPA)广泛用作各种反应中的酰化和烷基化试剂。它是一种强无机酸,具有优异的脱水性能。
应用
多磷酸可用于合成芳族砜,N-取代的酰胺和 4-氨基二苯甲酮。它也可用于脱水,Fischer-Indole 合成,Beckmann 重排和 Schmidt 重排反应。它可以用作合成各种芳族酮的催化剂。
PPA 可以在从尿素和甲醇合成碳酸二甲酯(DMC)的过程中用作催化剂。它还可作为该过程中产生的氨的吸收剂。PPA 可用于制备二氧化硅负载的多磷酸(PPA-SiO2),一种易于处理、可重复使用的非均相催化剂。

A facile and efficient synthesis of substituted indeno[2,1-c]quinolin-6(7H)-ones from a variety of α-acyl N-arylcinnamamides mediated by polyphosphoric acid (PPA) is described, and a mechanism involving the formation of a dicationic superelectrophile and subsequent double intramolecular nucleophilic cyclization reactions is proposed.
