arenes with aromatic aldehydes. This reaction has been extended to aromatic dialdehydes, such as terephthalic dicarboxaldehyde and isoterephthalic dicarboxaldehyde, for the efficient synthesis of diarylmethylbenzaldehydes, which are useful synthons for various organic transformations. Further, successful one step convergent synthesis of various synthetically useful anthracene derivatives from phthalaldehyde
发现BF 3-一水合物是一种有效的强酸催化剂,以及一种适用于芳烃与芳族醛的羟烷基化的有效的原溶剂化介质。为了有效合成二芳基甲基苯甲醛,该反应已扩展至芳族二醛,例如对苯二甲醛和异对苯二甲醛,它们对于各种有机转化都是有用的合成子。此外,还成功地完成了由邻苯二甲醛聚合合成各种有用的蒽衍生物的步骤。BF 3 -H 2 O价格便宜,可作为非氧化性强质子酸/超酸的有效替代品。
