ANSWER:
Solution 27P
(a)
Treatment of bromocyclohexane with lithium divinylcuprate gives the desired vinylcylohexane as product. Thus, the reaction is shown as follows:
(b)
Treatment of (bromomethyl)cyclohexane with lithium divinylcuprate gives the desired allylcylohexane as product. Thus, the reaction is shown as follows:
