The unusual transformation of β-aryl-β-haloacroleins into valuable triaroylbenzenes is reported by the first time. The convenient sequence takes advantage on the one step access to triaroylbenzenes. This work establishes that the presence of amine is required for the trimerization procedure since it is involved in the formation of iminium–enamine intermediate A.
首次报道了β-芳基-β-卤代
丙烯醛向有价值的三芳酰基苯的不寻常转化。方便的顺序在一步接触三芳酰基苯的过程中得到了利用。这项工作表明三聚过程中需要存在胺,因为它参与了
