Question

Can you also help with the reagents please

Part 5 out of 11 Choose the best option for the precursor to benzaldehyde. Dois OH

Answer 1

Let's see retrosynthesis, OH RH FGT Aldol condensation reaction. Synthon T T ci chlonnation reaction Synthons cit + IT synthetic equivalents Synthetic Cle Equivalents ГО И

Synthesis ETH Pet CH₂ CL In this step, we just do oxidation of yo alcohol to aldehyde by using PCC. a mild oxidising reagent. WJ Similarly, we can do oxidation of our other reacant. 해 РСС, CH₂Cl2 ri] Now, first we have to perform chlorination on benzaldehyde with tla in presence of fellz if C1-C! + fecl3 — feclz...CI-CI → CIO + HCI Fecla

Now by doing aldol condensation reach bet." (II) & (III) we get our Tr.
