Boron trifluoride-methanol. The Lewis acid, boron trifluoride, in the form of its coordination complex with methanol is a powerful acidic catalyst for the esterification of fatty acids. For example, esterification of free fatty acids was completed in two minutes with 12 to 14% boron trifluoride in methanol under reflux [236]. WebApplications of boron trifluoride etherate Hydroboration–oxidation reaction The cis addition of diborane to an alkene bond provides an extremely useful method of hydration. Diborane can be generated by the addition of sodium borohydride to boron trifluoride etherate in tetrahydrofuran or ether at 0 o-5 C. Diborane is the dimer of borane (BH 3 ride on right time 歌詞
