From equimolar mixts. of B2F4 and MenN(SiMe3)3-n (Q; n = 0-3), B2F4.Q (I) are formed at low temps. By elimination of Me3SiF I (n =2) gives II, which slowly decomps. at room temp. to [F2BNMe2]2 and (BF)n. The course of the reactions was studied by 11B and 19F NMR spectroscopy and by measuring the vapor pressures. According to the 11B and 31P NMR spectra the reaction of B2Cl4 with PCl5 or [Me4N]Cl in liq. HCl at 0.degree. does not yield [PCl4]2[B2Cl6] or [Me4N]2[B2Cl6] but gives [PCl4][BCl4}, PCl3, and BCl3 or [Me4N][BCl4] and BCl3 besides (BCl)n.
