Abstract:

The nonaborane B9H15 has been obtained in yields near 13 by the interaction of B5H11 with a surface of hexamethylenetetramine, CH26N4. Purification by high-vacuum distillation methods and by low-temperature crystallization raised to m.p. to 2.6 degrees vapor tension 0.8 mm. at 28 degrees. The formula was proved by quantitative decomposition to H2 and B and by a mol. wt. determination involving flash evaporation. The mass spectrum suggests the same substance as the B9H15 used for the X-ray determination of structure. The IR and B-11 magnetic resonance spectra are presented. Further experience with the synthesis of other polyboranes from B5H11 also is described. Author
