[Y:1].[H][H].[CH:4]([OH:7])([CH3:6])[CH3:5]>[Zn]>[CH3:5][CH:4]([CH3:6])[O-:7].[Y+3:1].[CH3:5][CH:4]([CH3:6])[O-:7].[CH3:5][CH:4]([CH3:6])[O-:7]The same reaction was done exactly the same way except no zinc was milled with the yttrium. The milled yttrium was reacted with isopropanol in the same way. There was very little evolution of hydrogen and work-up of the reaction solutions gave a yield of less than 10% for yttrium isopropoxide.
