In the conditions of mechanochemical activation and without the solvent cis-syn-cis-isomer of dicyclohexano-18-
crown-6, 4I-bromobenzo-18-crown-6, 5,5I-dibromoderivatives of proximal [0.6]biphenyl-20-crown-6 and [1.5]dibenzo-
18-crown-6 form complexes with potassium chlorochromate (KCrO3Cl) with ratio of 1:1 and 87-99% yields. At the
same time, reactivity of the cis-anti-cis-isomer of dicyclohexano-18-crown-6 is considerably lower: the yield of the
(1:1) complex in the similar conditions is only 10%, and benzo-18-crown-6 and [3.3]dibenzo-18-crown-6 do not take
part in the reaction.
