Phosphine,1,5-pentanediylbis[bis(1,1-dimethylethyl)- - Introduction

Pentane, 1,5-bis(di-t-butylphosphino)-, chemical formula C18H38P2, is an organophosphorus compound. The following is a description of the properties, uses, preparation and safety information of the compound:

Nature:
Pentane, 1,5-bis(di-t-butylphosphino)-is a colorless liquid with a characteristic phosphane odor. It is insoluble in water, but can be dissolved in many organic solvents (such as ethanol, dimethylformamide, etc.). This compound has strong lipophilic and antioxidant properties.

Use:
Pentane, 1,5-bis(di-t-butylphosphino)-is an important phosphine ligand widely used in organic synthesis. It can coordinate with transition metals to form stable complexes and play an important role in catalytic reactions. These reactions include hydrogenation, coupling, condensation, and C- H activation. In addition, it can also act as a reducing agent and stabilizer in the reaction.

Preparation Method:
A commonly used preparation method is to react 1,5-pentanediol with tert-butyl phosphonic acid chloride, and then go through a series of steps to obtain the product. Specific preparation details can be found in the literature and in chemical handbooks.

Safety Information:
Pentane, 1,5-bis(di-t-butylphosphino)-is relatively stable under normal operating conditions, and is not prone to spontaneous combustion or explosion at room temperature. However, it may decompose at high temperatures or in the presence of an open flame to produce toxic phosphine gas. Therefore, when in use, it is necessary to maintain good ventilation and avoid contact with open flames and oxidants. At the same time, the laboratory's safe practices should be followed and appropriate personal protective equipment, such as lab gloves and goggles, should be worn. During use and storage, care should be taken to avoid contact with oxygen and moisture to prevent danger. Observe local laws and regulations when handling or disposing of waste.
