Friedel-Crafts reaction of 1-(N-acylamino)alkyltriarylphosphonium salts with arenes or heteroarenes without the need for any catalyst provided access to a wide range of biologically interesting N-(1-arylalkyl)amides or 1-arylalkylphosphonium salts which can be of great interest in the chemistry of ylides and phosphonium ionic liquids. Depending on reaction conditions and substrate structure, the reaction
1-(N-酰基氨基)烷基三芳基phosph盐与芳烃或杂芳烃的Friedel-Crafts反应,不需要任何催化剂,提供了广泛的生物学意义上的N-(1-芳基烷基)酰胺或1-芳基烷基phosph盐的接触途径。对叶立德和phospho离子液体的化学非常感兴趣。取决于反应条件和底物结构,反应可以选择性地以高收率朝向上述每种产物进行。还考虑了上述转换的机械方面。
