If one were to want to aminate a mole of ketone, how much titanium (IV) would they use? It looks to be a catalyst of sorts, but all write ups so far claim that double the molar ratio of ketone to titanium (IV) is used (ie 10 mmol of ketone and 20 mmol (5.9 mL) of titanium). I doubt that one would use 600 mL of titanium (IV) for the 1 mole of ketone!
