A method for direct functionalization of polyaniline and other molecules with at least one diiminoquinoid ring through C—C bond formation is described. Fluoride ion, or a weak base whose conjugated acid form has a pK
a
value of 1-10, is used as a catalyst to react the molecule with an organic compound that has an abstractable proton directly bonded to the target carbon atom thereof to be bonded to the diiminoquinoid ring and has a pKa value less than 30 for the abstractable proton.
本文描述了一种通过C-C键形成直接对聚苯胺和其他至少含有一个二亚胺喹啉环的分子进行官能化的方法。使用氟离子或具有pKa值为1-10的共轭酸形式的弱碱作为催化剂,将具有可提取质子的有机化合物与目标碳原子直接结合的二亚胺喹啉环反应,其pKa值小于30。
