1298-55-1 - Introduction

Tris(cyclopentadienyl)samarium(Tris(cyclopentadienyl)samarium) is an organic compound containing samarium ions. Its chemical formula is [C5H5]3Sm, where C5H5 represents a cyclopentadiene group.

Nature:
Tris(cyclopentadienyl)samarium is an air-sensitive solid compound with the appearance of orange-yellow crystals. It has a high melting and boiling point. Tris(cyclopentadienyl)samarium slightly soluble in water at room temperature, but can be dissolved in some organic solvents such as toluene and diethyl ether.

Use:
Tris(cyclopentadienyl)samarium is mainly used as a catalyst in organic synthesis reactions. Samarium ion can be used as a strong Lewis acid to effectively catalyze the polymerization, addition and cyclization of olefins. In addition, it can also be used in reduction, oxidation and alkylation reactions in organic synthesis.

Preparation Method:
Tris(cyclopentadienyl)samarium are usually prepared by metal reduction methods. A specific preparation method involves reacting samarium metal with an excess of cyclopentadiene at an appropriate temperature and then purifying the product by solvent distillation.

Safety Information:
Since Tris(cyclopentadienyl)samarium is air-sensitive, avoid contact with air during handling. It should also be kept away from water and oxygen. Appropriate protective measures should be taken during handling or storage, such as wearing chemical protective gloves and goggles. In addition, Tris(cyclopentadienyl)samarium is also a toxic substance and should be kept away from children and follow relevant safety procedures.
