Sample Problem Show the intermediates and products that result from alkoxymercuration- demercuration of 1-methylcyclopentene, using methanol...
SOLVED PROBLEM 7-3 When the following compound is heated in methanol, several different products are formed. Propose mechanisms to account for the four products shown. CH-Br CH heat CH,OH -OCH; + -OCH PARTIAL SOLUTION With no strong base and a good ionizing solvent, we would expect a first-order reaction. But this is a primary alkyl halide, so ionization is difficult unless it rearranges. It might rearrange as it forms, but we'll imagine the cation forming then rearranging. H. Br: CH...
