T. Albrecht et al., 1,6-Bis(2,4,6-tri-tert-butylphenyl)-1,6-dibora-2,5-diaza-hexa-1,5-diine, the first compound containing two B equivalent to N triple bonds, CHEM COMMUN, (23), 1998, pp. 2583-2583
The elimination of hydrogen fluoride from N,N'-bis[(2,4,6-tri-tert-butylphe
nyl)fluoroboryl]ethylene 1 gives the title compound 2 as a thermally very s
table moiety; water is easily added across the B=N triple bonds.
