Show how you would synthesize the following compound from alkyl halides, vinyl halides, and aryl halides containing no more than six carbon atoms.
(d) cyclopentyl propyl ketone

What product is formed when 3-methyl-2-cyclohexenone reacts with each of the following reagents?

a. CH₃MgBr followed by H₃O⁺

b. (CH₃CH₂)₂CuLi followed by H₃O⁺

The Reformatsky reaction is an addition reaction in which an organozinc reagent is used instead of a Grignard reagent to add to the carbonyl group of an aldehyde or a ketone. Because the organozinc reagent is less reactive than a Grignard reagent, a nucleophilic addition to the ester group does not occur. The organozinc reagent is prepared by treating an α-bromo ester with zinc.

Describe how each of the following compounds can be prepared, using a Reformatsky reaction:

a.

Using bromocyclohexane as a starting material, how could you synthesize the following compounds?
