DIBROMOBIS(TRIBUTYLPHOSPHINE)NICKEL(II) - Introduction
Dibromobis(tributylphosphine)nickel(II) is a complex with the chemical formula NiBr2(PBu3)2. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
Dibromobis(tributylphosphine)nickel(II) is a solid, gray-white crystal at room temperature. The compound is stable in air, but is readily soluble in ethers, organic solvents and ketone solvents.
Use:
Dibromobis(tributylphosphine)nickel(II) is widely used in organic synthesis as an important transition metal catalyst. It can be used to catalyze the hydrogenation of olefins, the cyclopentadiene conjugate addition reaction of olefins, and the partial hydrogenation reaction of acetylene.
Preparation Method:
The preparation of Dibromobis(tributylphosphine)nickel(II) is generally obtained by reacting a nickel(II) salt with tributylphosphine in a solvent. For example, nickel(II) chloride and tributylphosphine can be reacted in tetrahydrofuran solution to form Dibromobis(tributylphosphine)nickel(II).
Safety Information:
When using and handling Dibromobis(tributylphosphine)nickel(II), it is necessary to comply with general laboratory safety regulations. This compound may cause irritation and damage to the skin, eyes and respiratory system, so appropriate personal protective equipment such as safety glasses, gloves and protective face masks should be worn during handling. In addition, the compound should be properly stored and protected from contact with oxygen, moisture and acidic substances to prevent possible dangerous reactions. It needs to be stored in a sealed container, away from fire and high temperature environment.
