Mechanism of the dehydrogenation of Mg(BH 4 ) 2 ·THF 0.25 to Mg(B 10 H 10 ): role of the THF solvate

Dehydrogenation of Mg(BH 4 ) 2 ·THF x at 180 °C under 20 bar of H 2 results in the highly selective, irreversible production of Mg(B 10 H 10 ). Slow convertion of THF to butoxide curtails the production 3 but can be revived by addition of THF.
