E-PHENYLETHENYLBORONIC ACID Usage And Synthesis

Chemical Properties	Brown granular powder
Uses	E-Phenylethenylboronic acid is a reagent used for• ;Palladium (Pd)-catalyzed Suzuki-Miyaura coupling reactions 1 Rhodium (Rh)-catalyzed intramolecular amination of aryl azides 2 Diastereoselective synthesis via Pd-catalyzed Heck-Suzuki cascade reaction 3 Copper (Cu)-mediated cyanation 4 Rhodium (Rh)-catalyzed asymmetric addition 5 Diastereoselective synthesis via iridium (Ir)-catalyzed addition 6 Palladium (Pd)-catalyzed cascade cyclization 7 Reagent used in Preparation of • ;Optically active unsaturated amino acids by diastereoselective Petasis borono-Mannich reactio
Uses	trans-beta-Styrylboronic acid as reagent is used for palladium (Pd)-catalyzed Suzuki-Miyaura coupling reactions, diastereoselective synthesis via Pd-catalyzed Heck-Suzuki cascade reaction and rhodium (Rh)-catalyzed intramolecular amination of aryl azides. It is also used as reagent in preparation of optically active unsaturated amino acids by diastereoselective Petasis borono-Mannich reaction and amino alcohol dienes via Petasis 3-component reaction using Ru-catalyzed ring-closing metathesis and isomerization.
