Antonio,

One thing that is wrong with this is that you have misused the shell 
quotes; you have tried to use ' inside ''. You could quote the patterns 
containing ' with "" instead of '', but you would also need to double up
the \ characters and it would be rather messy. Instead, you could avoid
shell quoting by putting the sed script in a separate file, like this:

sed -f mySedScript $archivo-copia > $archivo-out

where mySedScript contains:

s/\\'a/á/g
s/\\'e/é/g

and so on.

You can even begin the script with
#!/bin/sed -f
and invoke it like this if you wish:
mySedScript $archivo-copia > $archivo-out
