Sahoo, Ratikanta and Sweta Leena, Sushree (2012) Synthesis, Characterization and catalytic application of
polyphosphoric acid-Zr-pillared clay for the multicomponent synthesis of tetrahydropyridines. MSc thesis.
In this investigation, the structural and interlayer modifications of the clay material by intercalating zirconia polyoxocations as pillaring agent and polyphosphoric acid as active species have been reported. The physicochemical characteristic of these modified clay materials have been studied using various analytical techniques such as XRD, FTIR, UV-Vis techniques. XRD study signifies the expansion of the interlayer structure on pillaring of zirconia polycations. It also shows that the interlayer structure is retained even after thermal treatment at 5000C. FTIR and UV-Vis studies indicate the structural integrity of the PPA in the interlayer of the clay materials. The catalysts synthesized are employed for the synthesis of tetrahydropyridines. It has been found that ZrP-PPA intercalated materials are highly efficient for the multicomponent one pot synthesis of tetrahydropyridines.
