Methyltriphenylphosphonium Bromide (CAS 1779-49-3) Overview

A quaternary phosphonium salt widely used as a reagent in organic synthesis, particularly for Wittig reactions. White crystalline solid soluble in polar solvents like dichloromethane or DMF.

Basic Properties

Technical Specifications Comparison

Industrial Applications

1. Wittig Reaction Catalyst

Converts aldehydes/ketones to alkenes through phosphorus ylide intermediates. Reaction conditions: 60-80°C in THF/DMF with strong base (e.g., KOtBu).

2. Phase Transfer Catalyst

Facilitates reactions between immiscible phases in:
– Pharmaceutical intermediates synthesis
– Polymer modification processes

3. Ionic Liquid Precursor

Used in electrolyte formulations for lithium-ion batteries and supercapacitors.

Operational Guidelines

Reaction Setup Example

Procedure: Add phosphonium salt and base under N₂, stir at 65°C for 1hr before carbonyl addition.
