1,2-Bis((2S,5S)-2,5-diethylphospholan-1-yl)benzene - Introduction
()-1,2-Bis((2S,5S)-2,5-diethylphospholano)benzene is a chiral organic compound, its chemical formula is C22H32P2. The compound is a chiral molecule with two chiral centers. Its structure contains two 2,5-diethylphosphino alkyl groups attached to the 1,2 position of the benzene ring.
This compound is commonly used as a catalyst for ligands in asymmetric catalytic reactions. It can coordinate with transition metals to form complexes and participate in various catalytic reactions such as asymmetric hydrogenation, asymmetric olefin addition, etc. Its chiral structure makes it selective and can produce products with high enantioselectivity.
The preparation method can be synthesized by nucleophilic substitution reaction at two sites on the benzene ring. First, benzene is coupled to an appropriate chiral phosphine compound, and then the target compound is finally obtained through a series of reaction steps such as reduction, removal of the protecting group, etc.
This compound is widely used in catalytic reactions. It can be used in organic synthesis to prepare chiral drugs, pesticides, natural products is particularly important.
Regarding safety information, the specific data may vary depending on the manufacturer and place of origin, so it is recommended to read the product manual and safety data sheet carefully before use. In general, the treatment or use of the compound should be carried out in a well-ventilated area and avoid contact with skin and eyes. The storage of the compound needs to follow specific storage conditions, such as protection from light, drying and low temperature.
