CAS:14647-23-5 | [1,2-Bis(diphenylphosphino)ethane]dichloronickel(II)

[1,2-Bis(diphenylphosphino)ethane] dichloronickel(II), abbreviated as NiCl₂(dppe), is a coordination compound of nickel(II) chloride and the ligand 1,2-bis(diphenylphosphino)ethane. This nickel complex is widely used in organic synthesis and catalysis.

Properties：

1. It has a certain solubility in organic solvents (such as toluene and dichloromethane), but its solubility in water is low.
2. The nickel (II) center is coordinated by two chlorines and forms a four-coordinated planar complex with 1,2-bis (diphenylphosphine) ethane.
3 It has a certain stability in air, but may decompose in a humid environment or under light conditions.

Uses：

Organic synthesis catalyst:
[1,2-Bis(diphenylphosphino)ethane]dichloronickel(II) is used as a transition metal catalyst for coupling reactions (such as Suzuki-Miyaura and Stille coupling), olefin hydrogenation and C-H bond activation, and is particularly suitable for building carbon-carbon and carbon-heteroatom bonds.
Pharmaceutical and pesticide intermediates:
Participate in the synthesis of metal organic compounds containing phosphine ligands, and are used to develop anticancer drugs, antibiotics and new pesticides.
Research fields:
As a model compound to study the nickel catalytic mechanism, or to prepare functional materials (such as photoelectric material precursors).
