(R,R)-1,2-双[(2-甲氧基苯基)苯基膦基]乙烷 - Introduction
(R,R)-DIPAMP((R,R)-DIPAMP) is a chiral organophosphorus compound. Its molecular formula is C22H24O2P and its relative molecular mass is 354.4g/mol. It had the appearance of a white crystalline solid.
(R,R)-DIPAMP is an important ligand, which is widely used in organic synthesis. It can be combined with metal through coordination bonds to form metal complexes. These complexes often have good stereoselectivity and catalytic activity, and are widely used in asymmetric synthesis reactions. In particular, it plays an important role in the synthesis of chiral drugs, material chemistry and natural product synthesis.
The preparation method of (R,R)-DIPAMP is relatively complicated and is usually achieved through a multi-step reaction. A common synthetic method is by reacting phenylboronic acid with 2-methoxyphenyl bromide to give phenylphenylphenol, which is then reacted with (S,S)-1,2-diphenylethylenediamine to give (S,S)-1,2-diphenyl-1,2-dihydroxyethane. Finally, (R,R)-DIPAMP is obtained by reaction with tetramethyl lead chloride.
Regarding the safety information of (R,R)-DIPAMP, since it is a compound used in organic synthesis, laboratory safety procedures should be followed. It may be irritating to the skin and eyes, so use appropriate protective measures when exposed. At the same time, it should be stored in a dry, cool place, away from fire and oxidants. When handling and using, it is necessary to strictly control the amount and method of treating waste. It is recommended to operate under professional guidance.
