Treatment of the diborane(4) compound B2(NMe2)4 with aniline or 2,6-dimethylaniline results in the primary amido compounds B2(NHR)4
(R = Ph, 2,6-Me2C6H3); subsequent treatment with n-BuLi in toluene in each case affords the first examples of anionic imidodiborates namely Li4(thf)6B2(NPh)4 and Li4(thf)4B2(N-2,6-Me2C6H3)4; all complexes have been characterised crystallographically.

The new polycyclicborazines B(2)1,2-N(2)C(6)H(4)}(2)B(2)(NMe(2))(2)}(2), B(2)1,8-N(2)naph}(2)B(2)(NMe(2))(2)}(2) and B(2)(NPh)(4)B(2)(NMe(2))(2)}(2) have been prepared from diborate(4) anions and two equivalents of B(2)Cl(2)(NMe(2))(2) and have been structurally characterised. Aspects of their structure and bonding are discussed and comparison made with corresponding polycyclic aromatic hydrocarbons
