DIPHENYL(P-TOLYL)PHOSPHINE - Introduction
Diphenyl-p-tolylphosphine (abbreviated DPPB) is an organophosphorus compound. Its chemical formula is C19H19P and has two phenyl groups and one tolyl group attached to the phosphorus atom.
Nature of DPPB:
1. Appearance: DPPB is colorless crystals, the common form is solid.
2. Solubility: DPPB is soluble in organic solvents, such as ethanol, methanol and dichloromethane.
Purpose of DPPB:
1. Coordination chemistry: DPPB can be used as a ligand to form stable metal-organic complexes with metals. These complexes have important applications in catalytic reactions, such as reduction reactions, oxidation reactions and tandem reactions.
2. organic synthesis: DPPB can catalyze some key steps, such as C- C bond formation, C- N bond formation and alkyl halide aromatic substitution reaction.
3. Photoelectric materials: DPPB can be used in optoelectronic devices, such as organic light-emitting diodes (OLED), solar cells and chemical sensors.
Preparation of DPPB:
DPPB can be obtained by reacting phenyl sulfonic acid with dimethyl hydrogen phosphate. The reaction conditions need to be carried out in the absence of oxygen protection.
Safety information for DPPB:
1. attention should be paid to avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water.
2. operation should wear safety glasses and gloves. Be sure to operate in a well-ventilated area and avoid breathing in its vapors.
3. During storage and transportation, keep away from flammable substances and oxidants, and avoid contact with acidic substances.
Please note that the preparation and use of DPPB requires compliance with proper laboratory practices and safety practices. In order to ensure safety, please carry out relevant operations under the guidance of professionals.
