sodium added to ethanol creates sodium ethoxide.
can this be done with any other alcohols?
Methanol?

Thanks
is it possible to make 'sodium methoxide' and use this turn say, 2,5 di bromo benzaldehyde to 2,5 dimethoxy benzaldehyde (+ 2NaBr)
Also can this be done with other group 1 metals such as Li?

are used for transethylation of ester groups. Free hydroxy groups will not be methylated. Maybe you could use a quartenary ammonium salt for that?
It is good to have an end to journey toward;
but it is the journey that matters, in the end.
And there is sodium isopropoxide aswell

You could protect the aldehyde function of 2,5-dibromobenzaldehyde as the acetal, then react it with an excess of sodium methoxide in methanol using a catalytic amount of Copper(I)bromide, followed by hydrolysis of the acetal to get 2,5-dimethoxybenzaldehyde.
Both instructions for acetal formation and methoxylation can be found at my page, but exemplified for 3,4,5-trimethoxybenzaldehyde and 5-bromovanillin respectively.
