Understanding the effect of titanium species on the decomposition of alanates in homogeneous solution

It is known that a certain titanium species enhances the dehydrogenation of alanate, MAlH4 (M = Li and Na), in solid state. We carried out the dehydrogenation in solution in order to examine if the titanium species enhances the reaction under homogeneous condition as in solid state. The results show that the titanium species enhances the reaction in solution as well and that the titanium species interacts not only with hydride anions but also with counter cations.
