14. Synthetic Techniques

Show how you would synthesize 2-phenylhex-3-yn-2-ol, starting with acetophenone (PhCOCH₃) and any other reagents you need. ("2-ol" means there is an OH group on C2.)

Complete the following synthesis by providing the necessary reagents.

Beginning with the molecules on the left of each chemical equation, synthesize the molecules shown. While there can be multiple ways of doing each synthesis, the minimum number of steps necessary is indicated over each reaction arrow.
