APPLICATIONS |
||
|
Reagent used for the cis-vicinal diborylation of acetylenes and olefins with Pt catalysis; borylation of aromatics by Pd catalysis. Substrate used in a new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates. Used to construct a tetramethylpyrrolidine nitroxide scaffold for the synthesis of paramagnetic heterocycles by Suzuki coupling. Used as a specific functionalization or linear alkanes to form alkylboranes.An air-stable crystalline solid reagent for single step synthesis of boronic esters Pd-catalyzed one step conversion allowing access to boronic acid derivatives without protection of functionalities such as ester, ketone, cyano or nitro groups. |
