Question

Which reagent will convert $\mathrm{RCOR}\text{'}$ group into $\mathrm{RR}\text{'}\mathrm{C}\left({\mathrm{C}}_6{\mathrm{H}}_5\right)\mathrm{OH}$?

Answer 1

Grignard reagent

• The Grignard reagents can be used to make all three forms of alcohol (primary, secondary, and tertiary) by interacting with appropriate carbonyl compounds.
• Grignard reagents having the carbonyl group $\mathrm{C}=\mathrm{O}$ react with alcohol in aldehydes or ketones.

Convert $\mathbf{RCOR}\mathbf{\text{'}}$ group into $\mathbf{RR}\mathbf{\text{'}}\mathbf{C}\left(C_6{H}_5\right)\mathbf{OH}$

• The $\mathrm{RCOR}\text{'}$ group is converted into $\mathrm{RR}\text{'}\mathrm{C}\left({\mathrm{C}}_6{\mathrm{H}}_5\right)\mathrm{OH}$ by phenyl magnesium halide.
• The conversion reaction is as follows:
