There has been no known actual attempts at this synthesis using the enolate of acetone and a halobenzene in DMSO but it has been done in liquid ammonia , but other ketone enolates, such as pinacolone has been extensively studied in this medium.

There are no theoretical obstacles at all to why it would not work in the production of phenylpropanone. The reaction can be catalyzed by iron salts, oxygen or UV light.

For a more in-depth discussion of this synthesis, read Drone 's Enolate Phenylacetone Synthesis FAQ 1. PhenylPropanone can be made in a single step by a free-radical reaction between benzene and acetone.

The reaction relies upon the special oxidative powers of manganese III acetate , a compound easily prepared from potassium permanganate. The yield is relatively low, and requires high dilution of the reactants, but this can be improved, and the reaction is also applicable for other substituted benzenes, as can be seen in the comprehensive Manganese III acetate catalyzed aromatic acetonylation document on this site.

A mixture of Manganese III acetate dihydrate The reaction mixture was partitioned between ml ether and ml water. Warning: Thallium salts are exceedingly toxic, and may be lethal upon ingestion!

Handle with gloves only! A solution of Thallium III Nitrate 39g, mmol in ml methanol is added to a solution of alpha-methylstyrene The solution is extracted with ether, dried over MgSO 4 and the solvent distilled off, and the residue vacuum distilled to give The colorless crystals of Thallium III Nitrate trihydrate are filtered, washed with a little dilute nitric acid and dried in vacuo over phsphorus pentoxide.

Thallium III Nitrate mol wt is stable indefinitely if stored in tightly sealed bottles. The salt is readily soluble in methanol and dilute mineral acids.

The phosphonium salt was prepared by dissolving triphenyl phosphine This salt is slightly hygroscopic on exposure in air but can be stored indefinitely in a sealed container.

The ylid resulting from treatment of the phosphonium salt with base was found to be very unstable at room tempature, the characteristic red color dissappearing within a few seconds.

Potassium tert -butoxide 33 mmol in 15 mL of glyme was added with stirring over 5 minutes. At this point a solution of benzaldehyde 30 mmol in 5 mL of glyme was added over five minutes.

The mixture was allowed to warm to room temp over 1h and was then directly distilled, to give pure phenylpropanone enol methyl ether.

Phenylpropanone was conveniently prepared from the enol ether by mixing with one equivalent of water with 0. To a stirred solution of bromobenzene The combined extracts were washed with water, 1M hydrochloric acid and satd.

To a stirred solution of bromobenzene 60 mmol , isopropenyl acetate 9g, 90 mmol and dichloro- bis - tri-o-tolylphosphine palladium 0.

Trimethylaluminium 30ml of a 2M solution in toluene was added to a solution of benzyl cyanide 2.

Ethyl acetate was added and the mixture was vigorously stirred for one hour. The organic layer was washed with aqueous NaHCO 3 , brine and dried over MgSO 4.

Removal of the solvent gave 2. To ml. DRY FLASK attach a reflux condenser. Attach ml sep. Add 60 ml. Add Add 75 ml anhydrous ether to flask.

Allow aprox. If cloudiness does not become apparent in 1 or 2 min stop. Do not add more! Take a glass rod about 12 inches in length and score with a 3 corner file 2 inches from one end using pliers and a rag to protect your hands break away the 2 inch piece.

If reaction starts, add halide dropwise as quickly as the reflux column can handle. Be prepared to stop and cool with ice water bath if needed.
