Hi,

when a compound is assymetrical, and Bromine in CH3O- reagent is used, does the Br go to the less substituted carbon, while the OCH3 attaches itself to the more substituted carbon?

Thanks!

Bromine is highly selective it will prefer going to a tertiary>secondary>primary carbon in that order unless you have a benzylic in there as well then it will go to the benzylic tertiary. Also I believe you are talking in terms of markovnikov with the whole "assymetrical" thing :)
