Reaction Conditions:
with sodium methylate;Cu(2+)*4Cu(1+)*4I(1-)*2C5H3N2O2(1-)*C5H5N*C2H7N*3C3H7NO in ethanol at 25; for 1 h;Inert atmosphere;
Steps:
2.3. Typical procedure for the hydroborylation of alkynes
General procedure: The typical experimental procedure for the hydroborylation ofalkynes is as follows: a mixture of alkyne (2 mmol), compound 1(0.006 mmol), bis(pinacolato)diboron (2.5 mmol), NaOMe(0.2 mmol) and 5 mL EtOH were successively added into a reaction flask equipped with a Ar (99.99%) balloon. Then the flask was vacuumedand charged in Ar three times to exclude air in the reactionsystem. Subsequently, the obtained reaction mixture was magneticallystirred at 25 °C for 1 h. After the reaction was completed, thecatalysts were separated by filtration and the yield was determinedby GC analysis. The pure products were obtained by columnchromatography on silica gel (petroleum ether/ethyl acetate as aneluent).
