5112-95-8 - Introduction
BIS(DIPHENYLPHOSPHINO)ACETYLENE is an organometallic complex with the chemical formula C20H16P2, which is a colorless crystalline solid. The following is a description of its nature, use, preparation and safety information:
Nature:
BIS(DIPHENYLPHOSPHINO)ACETYLENE is an air-sensitive compound that reacts with oxygen to form phosphate esters. It has good solubility and is soluble in common solvents, such as ethanol, chloroform, etc. It is a coordination-active ligand that can form complexes with a variety of transition metals.
Use:
BIS(DIPHENYLPHOSPHINO)ACETYLENE can be used as a catalyst for asymmetric synthesis of ligands, with good catalytic activity and selectivity. It is commonly used in organic synthesis reactions, such as the synthesis of risedone, the synthesis of stearic acid double bonds, and the carbazole labeling of olefins.
Method:
A common preparation method is to obtain BIS(DIPHENYLPHOSPHINO)ACETYLENE by reacting diphenylmagnesium phosphide with bromoacetylene. The preparation process needs to be handled carefully, because bromoacetylene is a highly toxic and flammable substance, and the reaction should be carried out under an inert atmosphere.
Safety Information:
BIS(DIPHENYLPHOSPHINO)ACETYLENE should pay attention to safety during operation and storage, and avoid contact with air to avoid dangerous substances. It is flammable and explosive at high temperatures. In the process of use, wear protective gloves and glasses to ensure that the operating environment is well ventilated. At the same time, it is necessary to avoid contact with oxidants, strong acids and other substances to avoid dangerous reactions. In the case of accidental leaks, fire protection equipment should be used to avoid causing a fire.
