(S)-(+)-Neomenthyldiphenylphosphine - Introduction
(S)-( )-Neomenthyldiphenylphosphine (S)-NMDPP, abbreviated as (S)-( )-Neomenthyldiphenylphosphine or (S)-NMDPP. It is a chiral organic compound with the formula C19H23P. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
(S)-NMDPP is a solid, usually in the form of white crystals or crystalline powder. It is insoluble in water at room temperature, but soluble in many organic solvents, such as ethanol, methanol and dichloromethane. The compound has excellent chiral and stereoselectivity and can be used for chiral catalytic reactions.
Use:
(S)-NMDPP is often used as a chiral ligand for platinum metal complexes, especially in chiral catalytic synthesis. It plays the role of catalyst in asymmetric hydrogenation reaction and other organic synthesis, and can effectively control the selectivity and yield of the synthesis reaction.
Preparation Method:
(S)-NMDPP is generally prepared by a chiral chemical synthesis method. A common synthetic method is by reacting the dithioester with (1R)-(+)-quinoline to give the dithioester salt of (S)-NMDPP, which is then converted to (S)-NMDPP by hydrolysis or other methods.
Safety Information:
(S)-NMDPP is relatively stable and non-flammable under normal operating conditions. However, as organic compounds, general laboratory safety practices should be followed. Wear appropriate protective equipment to avoid contact with skin and eyes. Store in airtight containers and away from fire and oxidizers. If exposed or inhaled, medical attention should be sought immediately.
