By reaction of calix[4]resorcinarene with 2-ethyl-1,3,2-benzoxazaphospholine in 1:1 ratio we prepared a cavitand possessing one dioxaphosphocinic fragment on the upper circle of the molecule. Reaction of the same compounds in ether solution in 1:4 and 1:8 ratio according to the data of spectral methods leads initially to formation of addition product, the P-H phosphorane with composition 1:4. This compound is not stable and on keeping forms 2-oxo-2-ethyl-1,3,2-benzoxazaphospholine, spirophosphorane, omicron -aminophenol and phosphorylated calixarene. In the reaction of the aminoalkylated calixarene with 2-ethyl-1,3,2-benzoxazaphospholine we isolated a compound possessing four hydrophoshonyl fragments on the upper circle of the calixarene matrix.
