methanol–water. The wide scope and simple set-up and work-up procedures of the reported method allow the synthesis of a diverse set of α-aminophosphonic acids possessing two different functional groups. A total of 20 α-aminophosphonic acids are synthesized in 73–89% yields via a one-pot, three-step procedure involving chlorotrimethylsilane-promoted condensation of carbonyl compounds and primary amines yielding
Imine-linked covalentorganicframeworks (COFs) have received widespread attention because of their structure features such as high crystallinity and tunable pores. However, the intrinsic reversibility of the imine bond leads to the poor stability of imine-linked COFs under strong acid conditions. Also, their thermal stability is significantly lower than that of many other COFs. Herein, we report for
