I am trying to make 30mmol of benzyl t-butyl ether and im stuck. i have been instructed not to use distillation because of the high boiling point of the oily product. Also ive been instructed to use threefold excess of tert-butoxide and a 30 min reflux. I know I need 30 mmol of each starting material.Can someone help me??? Does three fold excess mean three times tert-butoxide than
