CAS 37972-24-0: 2-Ethynylpyrimidine

2-Ethynylpyrimidine

2-Ethynylpyrimidine is a ligand that binds to metals. It has been shown to be selective for copper and nickel, which have similar coordination geometries. The regioselectivity of 2-ethynylpyrimidine is due to the difference in the electronegativity of the nitrogen atom and the carbon atom on the ethynyl group. This ligand can bind to metal ions through coordination chemistry, where it forms a complex with a metal ion and coordinates with it. 2-Ethynylpyrimidine binds more strongly than other ligands such as butyllithium, which is also used in coordination chemistry. 2-Ethynylpyrimidine is used in spectroscopy to measure electron density and is often used as a heteroatomic ligand because it has an interesting spectrum. It can act as a chiral ligand because it can form two different enantiomers or stereoisomers. 2-Ethynyl
