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
