Efficient borylation of reactive aryl halides with MPBH (4,4,6-trimethyl-1,3,2-dioxaborinane).
Résumé
The combination of 4,4,6-trimethyl-1,3,2-dioxaborinane, a particularly stable and inexpensive borylation reagent, and Buch-wald's palladium catalyst provides a simple, fast, cost-effective borylation of electron-rich, reactive iodides, bromides, and tri-flates, to produce stable, easily purified boronic esters.
