97% | With C28H40CuNO In acetonitrile at 20℃; for 2h; Schlenk technique; Inert atmosphere; | A General Protocol General procedure: To a flame dried Schlenk was added Et2CAACCuOPh (2.5 mol %) and a magnetic stir bar under an Ar atmosphere. 0.097 mL freshly distilled MeCN was added to fully dissolve catalyst and yield a 2.3 ± 0.1 M solution depending on the nature of the alkyne. Alkyne (0.56 mmol, 1 eq.) was added followed immediately by pinacolborane (0.57 mmol, 1.025 eq). The resulting solution is stirred at room temperature for 2 hours. After this time, the volatiles were evaporated under vacuum. 10 mL pentane was added to residue. This solution was passed through a pad of silica (5 cm diameter x 5 cm high) to remove insoluble components. Elution with 2 x 10 mL of pentane, followed by evaporation under vacuum yielding pure products 2a-m. |
