摘要

A new heterogeneous MCM-41 silica supported HPF6 catalyst has been synthesized and characterized using an array of sophisticated analytical techniques like BET, XRD, HRTEM, EDX, 29Si MAS NMR, TGA, FTIR, and pH measurement. The broad applicability of silica- HPF6 was probed through a library synthesis of highly substituted 1, 4-dihydropyridines (1, 4- DHPs). The 1, 4-DHPs are further oxidized to pyridines with aqueous H2O2 as ...
