difluoroboron and chlorofluoroboron cations DD'BF2+ and DD'BFCl+ involving at least one C=N donor molecule can be formed by Cl- displacement from the mixedborontrihalideadducts D·BF2Cl and D·BFCl2, provided that the steric hindrance of D' and especially D is not too great. The DD'BF2+ cations can also be formed by selective displacement of one donor molecule in certain D2BF2+ cations, present in acetone as their
