Nano-size catalysts of TiO2, ZnO, CuO, and protonated trititanate nanotubes (H2Ti3O7) have been investigated for the one-pot three component synthesis of novel α-aminophosphonates from benzothiazole amines, heteroaldehydes, and dialkyl/diaryl phosphites via Kabachnik–Fields reaction. This methodology provides a new and convenient approach to multicomponent reaction and the H2Ti3O7 nanotubes catalyst is recyclable
研究了TiO 2,ZnO,CuO和质子化三钛酸盐纳米管(H 2 Ti 3 O 7)的纳米尺寸催化剂,用于由苯并噻唑胺,杂醛和二烷基/二芳基化合物一锅三组分合成新型α-氨基膦酸酯。通过Kabachnik-Fields反应生成亚磷酸酯。这种方法为多组分反应提供了一种新的便捷方法,H 2 Ti 3 O 7纳米管催化剂可循环使用多达七个循环。
