How do you prepare alkoxide?

Treat the parent alcohol with an alkali metal; alternatively, treat it with a lithium reagent.


#ROH(l) + Na(s) rarr RO^(-)Na^(+) + 1/2H_2(g) uarr#

This will work for methanol and ethanol.


#ROH + Bu^(-)Li^+ rarr RO^(-)Li^+ + BuH(g) uarr#

These alkali metal alkoxides usually have to be sublimed (twice!) to give the advertized reagent as pure materials.
