1,3,2‐Diazaborinium Compounds — New Cationic Boron Heteroarenes The diazaborinium cation 9 is obtained by the reaction of the vinamidine boron chelate 8 with Et 2 O—BF 3 . The cyclic aluminium compound 13 forms with the dichloroboranes RBCl 2 (R = Cl, Et, Ph) the cations 15,16a , and 16b . AM1 calculations demonstrate the π interaction of the boron with the nitrogen atoms as well as with the fluoro substituent.
