Reaction of resorcinol with phosphorylated acetals or ethoxyvinylphosphonic acid esters in acidic media leads to calix[4]resorcinarenes, containing dialkoxyphosphoryl fragments at the lower rim of the molecule. When the alkyl substituent in alkoxy groups at phosphorus atom is not very long, a partial hydrolysis of the initially formed products takes place to give calixarenes with alkoxyhydroxyphosphoryl fragments.
间苯二酚与磷酸化乙醛或乙氧基乙烯基膦酸酯在酸性介质中发生反应,生成钙[4]间苯二酚,分子下缘含有二烷氧基磷酰片段。当磷原子上的烷氧基中的烷基取代基不很长时,最初形成的产物会发生部分水解,生成含有烷氧基羟基磷酰片段的钙[4]间苯二酚。
