| Abstract: | It was shown that sulfur and phosphorus compounds (sodium thiosulfate, sodium tripolyphosphate, sodium hexametaphosphate, monosodium phosphate) catalyze cis-trans isomerization of aromatic heptaens. Preparative method of levorin isomerezation at the presence of sodium thiosulfate was elaborated. The isolated product was a fully trans-isomer. |
