What is Friedel-Crafts acylation, explanation of its mechanism with examples, how does it differ from alkylation, its practical applications, and limitations
1.In the presence of AlCl3 catalyst,octa(acetylphenyl) polyhedral silsequioxane(OAcPS) was synthesized by Friedel-Crafts acylation using polyhedral octaphenylsilsesquioxane(OPS) as starting material.以八苯基多面低聚倍半硅氧烷(OPS)为底物,无水三氯化铝为催化剂,经傅-克酰基化反应合成了笼形八(乙酰苯基)...
Friedel-Cr..在路易斯酸催化剂存在下,使用酰卤或酸酐将酮基添加到芳香族或脂肪族底物中称为Friedel-Crafts酰化。首先Lewis酸与酰化试剂络合,形成酰基氯路易斯酸络合物后转为酰基离子,这种酰基离子作为芳香
由于傅-克烷基化反应常常会生成重排以及多取代的副产物,所以除了分子内的烷化反应以外一般不常使用。但是,傅-克酰基化反应是吸电子取代反应,所以反应通常会停留在第一阶段。所以相对于烷基化反应,傅-克酰基化也常常被应用于分子间的反应。 基本文献 ・Friedel, ...
