4-BROMOBENZENEDIAZONIUM TETRAFLUOROBORATE Chemical Properties,Usage,Production

Chemical Properties

light beige to pink-beige powder

Uses

4-Bromobenzenediazonium tetrafluoroborate was used in preparation of surface modified Au(111) electrode, 1-(4?-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodec-1-ene.

General Description

Electrochemical reduction of 4-bromobenzenediazonium tetrafluoroborate was investigated for the derivatization of the carbon felt (modified carbon surfaces whether glassy carbon or carbon felt).

Purification Methods

Wash the salt with Et2O until the wash is colourless and allow it to dry by blowing N2 over it. Store it at 0-4o in the dark. [Schiemann & Pillarsky Chem Ber 64 1340 1931, Beilstein 16 III 517.]
