Popis: Tetra- and octa-phosphinanyl-ortho-methyl-tetra-C-naphthyl-resorcinarenes were alkylated with haloalkanes and ethyl bromoacetate. In all cases, the reactions followed the Michaelis-Arbuzov pathway to give phosphonates with haloalkyl groups at the periphery of the molecule. The O-alkylation of tetra-phosphato-ortho-methyl-tetra-C-naphthyl-resorcinarene with ethyl bromoacetate afforded a derivative with different functional sites at the horizontal and vertical benzene rings of the macrocycle, that is, phosphate and ethyl acetate sites, respectively. The exhaustive O-alkylation of ortho-methyl-tetra-C-naphthyl-resorcinarene afforded the octa(ethyl acetate) derivative, which was quantitatively transformed into the corresponding acid and amide.
