On Assembling Polychlorinated Aromatic Hydrocarbons from Carbon Tetrachloride via Dichlorocarbene Intermediary by A Solvothermal Reaction:  A Reaction Pattern from Carbene−Ylide Interconversion.

Spectrophotometric measurements on solutions of stannic iodide were found to provide evidence for complex formation with aromatic hydrocarbons. Calculations, based on spectra for mixed solutions of benzene and stannic iodide in carbon tetrachloride, yield values of 0.26 for the equilibrium constant (mole fraction), 28 400 1/mole cm for the molar extinction coefficient of the benzene – stannic iodide complex. Kinetic evidence indicates that the order of decreasing complex stabilities is from xylene to toluene to benzene. The formation of stannic iodide – aromatic hydrocarbon complexes provides an explanation for the discrepancy between measured solubilities of stannic iodide in benzene, toluene, and xylene, and the solubilities predicted by the Hildebrand theory of regular solutions.

Polychlorinated Aromatic Hydrocarbons

Oral and intraperitoneal treatment of rats with a single dose of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 33 microgram/kg, causes a 41--67% increase in iron adsorption in vivo. The major effect is on the transfer of iron from the mucosa into the bloodstream rather than on the uptake of iron from the lumen of the gut. These results are confirmed in studies with everted gut sacs. The effect is maximal at 1--2 days with a dose of 22-42 microgram/kg. Calcium transport is inhibited by TCDD treatment, whereas galactose and proline transport are unaffected. Treatment of rats with 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane also stimulates iron transport. Concomitant with iron transport stimulation, aryl hydrocarbon hydroxylase activity in the intestine and liver is increased by TCDD treatment. These studies suggest that polychlorinated aromatic hydrocarbons, which are environmental health hazards, may effect the intestinal absorption of essential mineral nutrients.
