on methyl/man reductive amination, swim will be using a 2liter round bottom.misskitty advised it wont be an easy stir, but the reflux takes care of most of the reaction. ive read its hard to beggin strring as it is with the foil weighing it down. (Now diffrent procedure, same question), with the MM benzo wacker, could swim get away with the rbf? any suggestion using this round bottom flask... thanks again!
