摘要

OH v\. Ill formed from t-butylbenzeiie by alkylatioii and isoiiierization. In support of this is the fact that t-butylbenzene does not survive the 45-hour benzenealuminum chloride treatment. The scope of this de-t-butylation reaction is indicated in Table 111. A11 of the benzophenones VI were de-t-butylated to VI11 in high yields except 2, 2'-dimethoxy-5-t- butylbenzophenone which suffered a side reaction to form xanthone. It will be noted that ...
