2-Butyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane Use and Manufacturing

Under argon, equipped with a 100 mL reaction flask was added 500mL of tetrahydrofuran 17. lg (0 · 10 mol) PinB (DMA), the temperature of the system was reduced to 0 ~ 5 ° C, dropping 44.3ml 2 · 5Μ positive butyllithium (0 · 11 mol), stirred at 0 ~ 5 ° C for 30 minutes, warmed to room temperature, stirring was continued for 2 hours, 200mL 1Μ KH2P04 buffer was added dropwise and the reaction was quenched with 150mL ethyl acetate three times. The combined organic phase was dried over anhydrous sodium sulfate, concentrating the organic phase, 40g of n-hexane to play with the public, and filtered to give a white solid:. 12 9g, yield: 70percent, GC> 97percent. 4 NMR, nB NMR and IR spectra consistent with the standard.
