Isolation of ?-Alkyl-iron(III) or Carbene-iron(II) Complexes from Reduction of Polyhalogenated Compounds by Iron(II)-porphyrins: the Particular Case of Halothane CF3CHClBr
FeII(TPP) (TPP = tetraphenylporphyrin) in the presence of an excess of sodium dithionite, reacts with CF3CCl3 and halothane CF3CHClBr, leading respectively to the carbene FeII (TPP)(CClCF3) and ?-alkyl-FeIII(TPP)(CHClCF3) complexes, the latter being the first isolated ?-alkyl-FeIII(porphyrin) complex involving a halogen substituent on the carbon bound to iron.

Improvements in or relating to contrast agents
Combined preparations comprising an injectable gas dispersion and a coadministrable diffusible component which is capable of inward diffusion into the dispersed gas so as to promote temporary growth of the gas in vivo, the preparations being for use as contrast agents in ultrasound cardiac studies of patients who have undergone physical exercise-induced stress in order to promote vasodilatation.

Enthalpy of Mixing of Liquid Binary Mixtures with Component Association. The System Oxolane (Tetrahydrofurane)-halothane (1,1,1-trifluoro-2-bromo-2-chloroethane)
The mixture halothane/oxolane was investigated to get information on kind and amount of associations occurring in the liquid phase.The indicators utilized were the IR absorbances and heats of mixing, which were processed exploiting a thermodynamic model which gives the association constants and other parameters.The results are compared mutually and with those pertinent to similar cases. - Keywords: Solutions / Associations / Oxolane / Halothane

SYNTHESIS AND SOME REACTIONS OF 2,3-EPOXY-2-CHLORO- AND 2,3-EPOXY-2-BROMO-6-HYDRODECAFLUOROHEXANES
Syntheses are reported for 2,3-epoxy-2-chloro- and 2,3-epoxy-2-bromo-6-hydrodecafluorohexanes and the reactions of these compounds with cesium fluoride, lithium aluminum hydride, and sodium borohydride were studied.The major site of nucleophilic attack in the case of 2,3-epoxy-2-chloro- and 2,3-epoxy-2-bromo-6-hydrodecafluorohexanes is C2 in contrast to 2,3-epoxy-6-hydroundecafluorohexane, in which the predominant nucleophilic attack occurs at C3 in the epoxide ring.The reaction of 2,3-epoxy-2-chloro- and 2,3-epoxy-2-bromo-6-hydrodecafluorohexanes with the fluoride ion is accompanied by replacement of the chlorine and bromine atom by fluorine.

Catalytic hydrogen-transfer reduction of polyhalofluoroalkanes using sodium hypophosphite
The catalytic hydrogen-transfer reduction of polyhalofluoroalkanes using sodium hypophosphite in the presence of a platinum or palladium catalyst is described.A selective reduction of carbon-bromine bonds could be performed under mild conditions.

Comparison of the Reactivity of CF3OX (X = Cl, F) with Some Simple Alkenes
Reactions of CF3OX (X = Cl, F) with a variety of simple alkenes were carried out to compare the regio- and stereoselectivity of the additions to carbon-carbon double bonds.The observed addition products with CF3OCl are consistent with an electrophilic syn addition.With CF3OF the observed products indicate a different regioselectivity and low stereoselectivity, consistent with a free-radical addition.
