Descripción

General description

Piperidine can be prepared either by nickel catalyzed hydrogenation of pyridine or by cobalt catalyzed hydrogenolysis of tetrahydrofurylamine It forms adducts with α,β,γ,δ-tetraphenylporphyriniron(II) and protoporphyriniron(II). Mossbauer spectra of these adducts have been evaluated. It constitutes the skeleton of various alkaloids. Its chemical reactivity has been discussed.

Application

Piperidine may be employed as protective and structure-directing agent in the post synthesis of MCM (Mobil Composition of Matter)-49 zeolites.
