CAS 2091-46-5: Phosphonium, triphenyl-2-propyn-1-yl-, bromide (1:1)

Description: Phosphonium, triphenyl-2-propyn-1-yl-, bromide (1:1), with the CAS number 2091-46-5, is an organic compound characterized by the presence of a phosphonium cation and a bromide anion. The structure features a central phosphorus atom bonded to three phenyl groups and a propynyl group, which contributes to its unique reactivity and properties. This compound is typically a solid at room temperature and exhibits good solubility in organic solvents due to its non-polar phenyl groups. It is often used in organic synthesis, particularly in reactions involving nucleophiles, as the phosphonium ion can act as a good leaving group. The bromide ion provides ionic character, enhancing its reactivity in various chemical transformations. Additionally, the presence of the propynyl group can facilitate further functionalization, making it a versatile intermediate in synthetic chemistry. Safety precautions should be taken when handling this compound, as with many organophosphorus compounds, due to potential toxicity and reactivity.
