Study On Synthesis Of Pyrrole Compouds

Pyrrole compouds commonly found in nature is a class of nitrogen-containing heterocyclic compouds. And, Pyrrole compouds has been applicated in the synthesis of many different serieses of polypyrrole. Polypyrrol is regarded as a very important electrochromic material. With the development of organic synthesis, many pyrrole compouds with complex structure have been synthesized, studied and applied. As a result, pyrrole compounds play a very important role in medicine, pesticides, materials, dye and many other areas. So we studied on synthesis of pyrrole compouds, and got a series of meaningful experimental results for further study:1. We used2,4-diphenyl-lH-pyrrole and1,2,4-triphenyl-lH-pyrrole as raw material reacting with different aryldiazonium salts to synthesy two kinds of pyrrole azo dyes. All the products are characterized by IR, UV-visible spectroscopy and NMR.2. We synthesized2-(2-pyridine)-4-phenyl-5-propyl-lH-pyrrol as new ligand. But it was not working. At last,2-(2-pyridine)-pyridine compouds and2-(2-pyridine)-quinoline compouds were used as ligand to synthesize [Cu(NN)(PP)]+compouds that were easier to be isolated. All the products are characterized by IR and NMR. Crystal X-ray diffraction is also used to characterize the products.3. We synthesized benzyl compouds by benzoin condensation reaction catalyzed by the carbin salt.Then we used benzyl compouds as raw material reacting with NH4OAc, synthesized oxazole compouds and imidazole compouds. All the products are characterized by IR and NMR.
