Application

4,4,5,5-Tetramethyl-1,3,2-dioxaborolane may be used for:

• Borylation at the benzylic C-H bond of alkylbenzenes in the presence of a palladium catalyst to form pinacol benzyl boronate.
• Hydroboration of alkyl or aryl alkynes and alkenes in the presence of transition metal catalysts.
• Coupling with aryl iodides in the presence of a copper catalyst to form aryl boronates.
• Asymmetric hydroboration of 1,3-enynes to form chiral allenyl boronates.
