Although many Borinato-transition metal-complexes have been isolated after the first synthesis and characterisation of such a molecule in 1970, nobody succeeded so far in isolating the unsubstituted neutral ligand Borine (Borabenzene) C5H5B.It is the aim of this theoretical investigation to find at least a partial answer to the question why the free borine should be a highly reactive molecule.The results of semiempirical and ab-initio-calculations presented here show that the LUMO of the free and unsubstituted borine in contrast to benzene and pyridine should be a σ*-molecular orbital which causes pronounced σ-acceptor properties.
