Question: What alkyl halides would you use to prepare the following ketones by an acetoacetic ester synthesis?

Short Answer

Expert verified

The alkyl halides which you need to use to prepare ketone (a) is 1-bromo-2-methylpropane.

The product of this reaction is

Hence, the-CH2COCH3comes from acetoacetic ester.

The remaining part CH32CHCH2 comes from alkyl halide (1-bromo-2-methylpropane).

Now the mechanism of this reaction is

Step by step solution

01

Subpart (a)

The alkyl halides which you need to use to prepare ketone (a) is 1-bromo-2-methylpropane.

The product of this reaction is

Hence, the-CH2COCH3comes from acetoacetic ester.

The remaining part CH32CHCH2 comes from alkyl halide (1-bromo-2-methylpropane).

Now the mechanism of this reaction is

02

Conclusion

The alkyl halide which you need to use to prepare the given ketone (a) by acetoacetic ester is 1-bromo-2-methylpropane.

03

Subpart (b)

The alkyl halides which you need to use to prepare ketone (b) is 1-bromo-2-phenylethane.

The product of this reaction is

Hence, the 鈥揅H2COCH3 comes from acetoacetic ester.

The remaining part C6H5CH2CH2- comes from alkyl halide (1-bromo-2-phenylethane).

Now the mechanism of this reaction is

04

Conclusion

The alkyl halide which you need to use to prepare the given ketone (b) by acetoacetic ester is 1-bromo-2-phenylethane.
