SYNTHESIS OF heme-DICHLOROSUBSTITUTED CYCLOPROPANES BY DICHLOROCYCLOPROPANATION OF LIQUID PYROLYSIS PRODUCTS OF THE OIL HYDROCARBONS
Under the conditions of interphase catalysis the dihlorcyclopropanation of fraction C5 of liquid pyrolysis products of the oil hydrocarbons was carried out and heme-dichlorosubstituted vinyl cyclopropanes and tetrachlorobicyclopropyls have been synthesized. The optimal conditions of preparation of these compounds have been found. The possibility of carrying out the dichlorocyclopropanation reaction of non-fractionated liquid pyrolysis products has been revealed and it has been shown that in this case, along with mono- and bis-adducts, the addition products of dichlorocarbene to alkenes being a part of pyrocondensate are formed.
