A method for the synthesis of 4′-bromobenzodithia-15(18)-crown-5(6) and 4′-bromobenzodiaza-15 (18)-crown-5(6) by condensation of 3,4-di(2′-haloethoxy)bromobenzene with polyoxaalkanes containing terminal SH or NHMe groups was suggested. The method for the synthesis of formyl derivatives of benzocrowns containing N, S, and O heteroatoms in the macrocycle based on the metallation of appropriate bromo
