- 論文の詳細を見る
The reaction of 1-ethoxycarbonyl-1<I>H</I>-azepine with chlorosilane derivatives in HMPA in the presence of magnesium afforded the silanol derivatives, which upon heating gave the corresponding siloxane derivatives. In the same manner, tropone and 2,5-dimethyl-3,4-diphenylcyclopentadienone afforded the reduced dimers of them. However, tetraphenylcyclopentadienone and 2,5-dimethoxy-3,4-diphenylcyclopentadienone were reduced to the corresponding cyclopentenones under the reaction conditions. These reactions are considered to proceed <I>via</I> the corresponding radical anions which are formed by electron transfer from magnesium.
