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.

1- and 2-alkoxy- or dialkylaminovinylphosphonates were synthesized using reactions of the corresponding vinylhalides with di- and triethylphosphites in the presence of catalytic amounts of Ni salts and Pd complexes. The best way for synthesis of I-alkoxy or dialkylaminoderivatives is the Pd-catalyzed cross-coupling reaction with (EtO)(2)POH and the best way for 2-alkoxy- or dialkylaminovinylphosphonates is the Arbuzov reaction with (EtO)(3)P catalyzed by Ni salts.
