HAFNIUM DIETHYLAMIDE - Introduction

Tetrakis(diethylamino)hafnium(IV), of the formula Hf(N(C2H5)2)4, is an organic hafnium compound. The compound is in the form of a yellow powder and is soluble in non-polar solvents such as benzene and carbon disulfide.

Tetrakis(diethylamino)hafnium(IV) can be used as catalysts in certain chemical reactions, especially in hydrogenation reactions and carbon-hydrogen bond activation reactions in organic synthesis. It can also be used as a pre-denitrification agent to remove nitrogen contaminants.

Preparation of Tetrakis(diethylamino)hafnium(IV) can be obtained by reacting diethylamine with hafnium chloride under N2 atmosphere. The reaction is usually carried out under an inert atmosphere to avoid the influence of air and moisture.

When using this compound, necessary safety measures need to be taken. Tetrakis(diethylamino)hafnium(IV) is irritating to the skin and eyes and may cause allergic reactions. Therefore, avoid contact with skin and eyes during handling and storage, and take appropriate protective measures, such as wearing gloves and goggles. At the same time, it should be operated in a well-ventilated place, away from fire and sparks.
