Application
1,2-Dibromoethane can be used:
- To prepare functionalized styrenes by reacting with arylboronic acids via palladium-catalyzed cross-coupling reaction.
- Along with potassium iodide(KI) for α-acyloxylation of ketones with carboxylic acids without the use of transition metals and strong oxidants.
- In the synthesis of 5-aryl/alkyl-2-vinyl-2H-tetrazoles through one-pot regioselective vinylation of 5-tetrazoles without a metal catalyst or organocatalyst.
- In the preparation of aryltriethoxysilane using aryl bromide, Mg powder and tetraethyl orthosilicate through sonochemical Barbier-type reaction.
- As a reoxidizing reagent along with a silver catalyst in the regioselective carbomagnesiation of terminal alkynes with alkyl Grignard reagents.
