Reaction Steps
About 82 mL of BCl3 is added dropwise over 30 minutes to a stirred solution of dry pinacol in pentane (1.3 L) at −30° C. The reaction mixture is stirred at 20° C. for 1 hour. A solid byproduct, B2[(OCMe2)2]3 is removed by filtration. The remaining solution is distilled to give about 90 grams of 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.
