文摘
- •
High heating rate decomposition of [AlBr(NEt3)]4 detected Al and AlHx species.
- •
Decomposition occurs at ∼220 °C with a determined activation energy of ∼43 kJ/mol.
- •
Addition of KIO4 resulted in increased Al, AlO, and HBr signal intensities.
- •
Gas phase oxygen from KIO4 oxidized the cluster during decomposition.
