It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid” because of its versatility and the relative inertness of the B-C bonds. Related fluoro-substituted boron compounds, such as those containing B-CF3 groups, decompose with formation of B-F bonds. ==Preparation== Tris(pentafluorophenyl)borane is prepared using a Grignard reagent derived from bromopentafluorobenzene. :3C6F5MgBr + BCl3 → (C6F5)3B + 3MgBrCl Originally the synthesis employed C6F5Li, but this reagent can detonate with elimination of LiF.〔Piers, W.
