What Grignard reagent and what carbonyl compound might you start with to prepare the following alcohol? но сна -CH₃ • Draw the Grignard reagent as a covalent magnesium bromide. • Any ester used should be a methyl ester. • If there is more than one combination, draw only one. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate multiple reactants using the + sign from the drop- down menu....

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
Part A What two distinct combinations of Grignard reagent and aldehyde could be used to prepare the alcohol below? OH Draw the molecules on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. o 9 C H* 12D 1 EXP. L CONT. 0 1 H + с
Tertiary alcohols with two identical alkyl groups attached to the alcohol carbon can be made either from an ester and two moles of a Grignard reagent, or from a ketone and one mole of a Grignard reagent. Use retrosynthetic analysis to suggest one path of each type to synthesize 1,1-diphenyl-1-propanol. (Click and drag the appropriate image to the correct position in the following reactions.)
