Preparation of Phenylacetone: 
It can be obtained by many methods. A conceptually simple example of phenylacetone organic synthesis is the Friedel-Crafts alkylation of benzene with chloroacetone.


Uses of Phenylacetone: 
It is used in the manufacture of methamphetamine and amphetamine. It is also used as intermediate of rodenticide diphacinone and chlorophacinone. In addition, this chemical can be used in many organic synthesis. For example: it can react with 2-chloro-acetamide to get 5-methyl-4-phenyl-1,3-dihydro-pyrrol-2-one. This reaction needs reagent t-BuOK and solvent dimethylsulfoxide at temperature of 80 °C. The reaction time is 3 hours. The yield is 35%.
