The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada
Masters Theses
The dianions of phenylacetone and its para-substituted derivatives were generated using potassium hydride and n-butyl lithium in tetrahydrofuran. Methyl, ethyl, and n-butyl iodides were used to alkylate the dianions. The results of alkulation indicated that C1 is preferentially attacked by the less active ethyl and n-butyl iodides. The results further show that terminal alkylation is enhanced by electron-donating groups at the para-position of the phenyl ring. The results are rationalized in terms of the difference in electron density at C1 and at C3 in the dianion, on the basis of resonance theory. The regio-selectivity of alkylation as …
