Preparation of Triphenylborane: It is typically made with boron trifluoride diethyl etherate and the Grignard reagent, phenylmagnesium bromide. The equation is as follows: BF3•O(C2H5)2 + 3 C6H5MgBr → B(C6H5)3 + 3 MgBrF + (C2H5)2O. It can also be synthesized on a smaller scale by the thermal decomposition of trimethylammonium tetraphenylborate. The equation is as follows: [B(C6H5)4][NH(CH3)3] → B(C6H5)3 + N(CH3)3 + C6H6.
Uses of Triphenylborane: it can be used to make triarylborane amine complexes, such as pyridine-triphenylborane. And it can react with acetic acid cyclohex-2-enyl ester to get 3-phenyl-cyclohexene. This reaction will need catalysts palladium bis(dibenzylideneacetone) and PPh3, and solvent tetrahydrofuran. The reaction time is 12 hours at reaction temperature of 60 °C. The yield is about 52%.
When you are using this chemical, please be cautious about it as the following:
