| Abstract: | A method for the synthesis of new calix4]resorcinols tetra-3,5-di-tert-butyl-4-hydroxybenzyl derivatives is developed. Their interaction with methyldichlorophosphonate, dimethyldichlorosilane in the presence of a base leads to formation of organophosphorus-organosilicon cavitands. Acetylation of hydroxybenzylated calix4]resorcinols with acetic anhydride leads to products of either incomplete or full acetylation depending on experimental conditions. |
