WebPentaborane (9), nido -B 5 H 9, is by far the most studied borane in this group. It can be prepared by passing a 1:5 mixture of B2 H 6 and H 2 at subatmospheric pressure through a furnace at 250°C with a residence time of 3 s (or at 225° with a 15 s residence time); there is a 70% yield and 30% conversion.

Pentaborane(9)
WebPentaboron nonahydride, stable pentaborane, or pentaborane (9) is a chemical compound that was considered a good prospect for a rocket or jet fuel by both the US and Russian armed services in the 1950s, a so-called “exotic fuel.”. It is one of the boranes, with a chemical structure of five atoms of boron and nine atoms of hydrogen (B 5 H 9 ). WebThe most important boranes are diborane B 2 H 6, pentaborane B 5 H 9, and decaborane B 10 H 14. The development of the chemistry of boron hydrides led to new experimental techniques and theoretical concepts. Boron hydrides have been studied as potential fuels, for rockets and for automotive uses.
