Chemical Properties
white to almost white fine crystalline powder
Uses
Used for corrosion inhibition of iron
Reactant involved in:
- Acting as a potential electrophile
- Elimination reactions for the synthesis of linear alkynes
- Intramolecular nucleophilic vinylic substitution
- Homologation of aldehydes
- Endo-selective alkynol cycloisomerization
Uses
(Chloromethyl)triphenylphosphonium Chloride is a Wittig reagent.
Preparation
(Chloromethyl)triphenylphosphonium chliride is available commercially (chloride or iodide salt) or synthetically from Triphenylphosphine and Chloroiodomethane.
Reactivity Profile
(Chloromethyl)triphenylphosphonium chliride is a precursor to the chloro-substituted ylide for Wittig reactions with aldehydes and ketones to form 1-chloroalkenes and, after elimination of HCl, terminal alkynes.
reaction suitability
reaction type: C-C Bond Formation
Precautions
For best results the anhydrous salt should be used. The ylide, formed from the salt and strong base, will react with air, water, or other acidic protons
