Butyltriphenylphosphonium bromide Usage And Synthesis

Chemical Properties

white crystalline powder

Uses

suzuki reaction

Uses

Reactant for: Free radical 5-exo-dig cyclization Intramolecular hydroacylalkoxylation Wittig reactions for stereoselective synthesis of alkenes Dimerization of α-olefins Alkylidenation of hydrazides for synthesis of indoles Tandem cyclization and 1,2-thiolate shift of nitrogen ylides

Uses

n-Butyltriphenylphosphonium Bromide is used in the synthesis of inhibitors of tubulin polymerization thus expressing antimitotic and antitubulin properties. Also used in the synthesis of 3-phenylpropanoic acids as peroxisome proliferator-activated receptor dual agonists affecting the mitochondrial carnitine system.

Uses

PTC catalyst

reaction suitability

reaction type: C-C Bond Formation

Synthesis

Under nitrogen protection, 280 g of bromobutane and 696 g of triphenylphosphine were added to a 2 L four-neck flask dissolved in 500 mL of xylene. The reaction mixture was heated to reflux temperature with continuous stirring for 6 hours. After completion of the reaction, the system was cooled to room temperature, the precipitated white crystals were collected by filtration and washed with xylene. After drying, 797 g of butyltriphenylphosphonium bromide was obtained as a white solid in 97.7% yield.
