Abstract:
In the first section of the present thesis, a number of novel heterocycles were prepared; they include spirodihydropyridine, spiroindoline-2-thion, and pyrrolopyrimidines. The major advantages of the current investigation encompass high yields, short reaction times, mild reaction conditions and feasibility and low-cost materials. In the second section of this thesis, heterogeneous catalysts based on magnetic nanoparticles coated with organosilanes were synthesized. These catalysts were synthesized by hydrolysis of tetraethyl organosilanes and other organosilicons such as 3-aminopropyl triethoxy silane. The synthesized scaffolds were used to stabilize precious metals as Pd and Cu. The magnetic properties of the catalysts aid to easy separation from the reaction medium by an external magnetic field. High thermal stability low toxicity and high-level loading of metals are some beneficiaries of the magnetic catalysts. In the end, catalytic properties of resulted catalyst were investigated in many types of organic reaction such as Click and oxidation and reduction reaction
