how to prepare acetone from grignard reagent

Answer 1

How can I synthesis acetone from Grignard Reagent?

Is the New Pension Scheme good for tax saving? Being an SBI account holder, can I avail it?

acetone is obtained from grignard reagent by using acetaldehyde.

for example:

1st step:

CH3_CO_H + CH3_Mg_Br → CH3_CHCH3_O_Mg_Br (in the presence of polar solvent)

2nd step:

CH3_CHCH3_O_Mg_Br → CH3_CHOH_CH3 + HO_Mg_Br (in the presence of H+ / OH-)

3RD STEP:

CH3_CHOH_CH3 + [O] → CH3_CO_CH3 + H2O (IN THE PRESENCE OF Cu)

acetone is obtained from grignard reagent by using acetaldehyde.

CH3_CO_H + CH3_Mg_Br → CH3_CHCH3_O_Mg_Br (in the presence of polar solvent)

2nd step:

3RD STEP:

CH3_CHOH_CH3 + [O] → CH3_CO_CH3 + H2O (IN THE PRESENCE OF Cu)

But this process is very expensive and unreliable. therefore it is not used to produce acetone which makes waste of time metarial and money.
