AI Article Synopsis
- The aluminum analogue of Piers' borane, referred to as [HAl(CF)]1, has been successfully synthesized in large quantities.
- DFT calculations indicate that this compound exhibits a greater fluoride ion affinity compared to Piers' borane, and the Al-H bond serves as a strong hydride donor, leading to reactions with alcohol and terminal alkynes.
- The compound [HAl(CF)]1 also demonstrates catalytic properties, promoting the hydrosilylation of both alkynes and alkenes.
Article Abstract
The aluminum analogue of Piers' borane, [HAl(CF)]1, is prepared on a gram-scale. Density functional theory (DFT) calculations reveal 1 has a higher fluoride ion affinity (FIA) than Piers' borane, while the Al-H moiety proved to be a strong hydride donor, reacting with alcohol and terminal alkyne to give the corresponding dehydrogenative products 3 and 4. Hydroalumination product 5 was prepared reaction of 1 with aldehyde. In addition, 1 catalyzes the hydrosilylation of alkynes and alkenes.
