Question

Hi there, can anyone help with the following problem?
The answer needs to me using the Suzuki-coupling mechanism.

Thanks so much!

1.Give one possible synthetic route in each case for the following two liquid crystals (A and B). O2C 120 marks] NOTES for question 1: You should start in each case with at least three commercially available precursors H HI ii!(with 2-Carbon atoms or more). Only reaction reagents and solvents and the appropriate order of synthesis should be givens reaction mechanisms are not needed

Answer 1

The retrosynthetic analysis and synthetic routes of compounds A and B are given below. The reaction conditions and reagents used are described on each reactions. The synthesis if given by step-wise and self explained. the question did not ask for machanism, so the reactions and their products are mentioned. Name reactions are also mentioned at proper step.
