How would you carry out the synthesis below? Additional carbons may come from any alkyl halide with 3 C's or less. Show the reagents needed for each step of your transformation, but do NOT draw the mechanisms for each step. SHORT ANSWER #30: How would you carry out the synthesis below. Additional carbons may come from any alkyl halide with 3 C's or less. Show the reagents needed for each step of your transformation, but do NOT draw the mechanisms...
2. Propose a synthesis of each of the following molecules beginning with any alkyl halide and another neutral molecule. Choose your reagents carefully to try to favor a single mechanism (for example, charged versus neutral nucleophile/base). If you would like to use a charged molecule in your synthesis you should show the formation of that molecule from the neutral species. Pay attention to stereochemistry a. b.

In the Williamson ether synthesis, an alkoxide ion reacts with an alkyl give an to halide ether R-O- + R-x rightarrow R-O-R + X^- To prepare sec-butyl propyl ether by this synthesis, is it better to use sec-butoxide ion and propyl chloride or propoxide ion and sec-butyl chloride? Explain your answer.
Draw an alkyl halide and an alkoxide ion that can be used to prepare the following ether using a Williamson ether synthesis.

The acetoacetic ester synthesis is a carbonyl alkylation reaction. It is used to prepare methyl ketones from primary alkyl halides, lengthening the carbon chain by three atoms. Thus, the product can be visualized as being a "substituted acetone." The reaction consists of three steps: generation of the enolate anion followed by S2 reaction with a primary alkyl halide, ester hydrolysis under acid conditions, and decarboxylation. 1. NaOEt 2.
