- 論文の詳細を見る
Photoreaction of ethyl chloroacetate with cumene gives ethyl cumenylacetates (17.5%) in the ratio <I>o</I> : <I>m</I> : <I>p</I> = 17 : 46 : 37. The same reaction with <I>t</I>-butylbenzene gives ethyl <I>t</I>-butylphenylacetate (23%) in the ratio <I>o</I> : <I>m</I> : <I>p</I> = trace : 65 : 35. Addition of BF<SUB>3</SUB> increases the total yield of the substitution products. Orientations together with those for toluene and anisole in ethoxycarbonylmethylation were discussed in terms of INDO-type MO calculation of the lowest singlet excitation energies.
