Polylithiation reactions of 1,3,5- and 1,2,4-trimethoxybenzenes have been investigated. Results showed that it is possible to substitute all arylic hydrogens through one-pot sequential bimetalation/monometalation, monometalation/bimetalation or three monometalations. This reaction is strongly affected by steric hindrance.
已经研究了1,3,5-和1,2,4-三甲氧基苯的多晶化反应。结果表明,可以通过一锅顺序双金属化/单金属化,单金属化/双金属化或三个单金属化来取代所有芳基氢。该反应受位阻强烈影响。
