Investigation of DMAB oxidation at a gold microelectrode in base
Rohan, James F.
Nagle, Lorraine C.
A gold microdisk has been used to determine the diffusion coefficient Formula for dimethylamine borane (DMAB) in concentrated alkaline solution. Two steady-state oxidation waves were resolved through the use of microelectrodes. Using the Formula value determined, the coulomb number for both oxidation waves was shown to be 3. The first wave may be further resolved in dilute solutions revealing three one-electron steps. The concentration range wherein the maximum coulombic efficiency for DMAB oxidation on gold may be achieved is demonstrated. An oxidation pathway with a variable coulomb number is suggested.
