Uncatalyzed Friedel−Crafts Alkylation of Aromatic Compounds through Reactive Benzyl Cations Generated from N-Sulfamoylcarbamates
摘要:
[GRAPHICS]A new method for the generation of highly reactive benzyl cations by thermal decomposition of aryl-benzyl-sulfamoylcarbamates, obtained in a one-pot reaction from chlorosulfonyl isocyanate, is described. The generated cations alkylate aromatic compounds efficiently in the absence of catalysts.
An efficient in situ prepared superacid BF3–H2O promoted benzylation of arenes using benzyl alcohols and acetates achieves various diarylalkanes.
一种高效的原位制备的超强酸BF3-H2O促进的芳烃苄基化反应,使用苄醇和醋酸酯制备各种二芳基烷烃。
