1,2,4,5-Tetraaza-3,6-diborinane monomers and dimers

Article abstract of DOI:10.1021/ic50083a013

The thermal decomposition of hydrazine-t-butylborane has been examined and the product has been identified as a polyhedral cage compound, a dimer of 3,6-di-t-butyl-1,2,4,5-tetraazadiborinane (VIII). Nuclear magnetic resonance data for this compound and its derivatives with methyl isocyanate are presented and discussed in relation to their structures. Proton-exchange studies of VIII and its derivatives were monitored by nmr. Attempts to dimerize 3,6-diphenyl-1,2,4,5-tetraaza-3,6-diborinane (I, R = C₆H₅) provided the same product as thermal decomposition of hydrazine-phenylborane. This product is not a polyhedral cage compound.
