Decaborane: From Alfred Stock and Rocket Fuel Projects to Nowadays †

The review covers more than a century of decaborane chemistry from the first synthesis by Alfred Stock to the present day. The main attention is paid to the reactions of the substitution of hydrogen atoms by various atoms and groups with the formation of exo-polyhedral boron–halogen, boron–oxygen, boron–sulfur, boron–nitrogen, boron–phosphorus, and boron–carbon bonds. Particular attention is paid to the chemistry of conjucto-borane anti-[B(18)H(22)], whose structure is formed by two decaborane moieties with a common edge, the chemistry of which has been intensively developed in the last decade.
