Descrição

Descrição geral

Iron(III) chloride hexahydrate can be obtained from crystallization of iron(III) chloride from water. Three-dimensional single-crystal X-ray-diffraction studies of its crystal structure suggest its crystals are monoclinic and C_2h³-2/m space group.

Aplicação

Iron(III) chloride hexahydrate (FeCl₃.6H₂O) may be employed as an oxidant for the following conversions:

• Synthesis of 2-substituted 4(3H)-quinazolinones (yield = 77-93%).
• Oxidation of 1,4-dihydropyridines (1,4-DHPs) to corresponding pyridines.
• Oxidation of 4-isopropyl-1,4-DHP to dealkylated pyridine.
