The isotope dilution method has been employed to determine isomer distributions in the nitration of chloro-, bromo- and iodobenzenes and the relative reactivity of iodobenzene with respect to benzene. For nitration at 25o, the following isomer distri

The mechanism of sulfonation of 4-hydroxyazobenzene and of 4-hydroxyazobenzene-4′-sulfonic acid in concentrated sulfuric acid media is examined through rate correlations and comparison is drawn with sulfonation of alkyl- and halogenobenzenes by mea

The photolysis of azoethane at λ 3660 Å has been reinvestigated. The quantum yield of nitrogen formation was found to be dependent on the azoethane pressure and the temperature, indicating collisional deactivation of excited azoethane molecules.The

Synopsis The radioactive decay of 112Pd → 112Ag → 112Cd has been investigated both with a βγ-coincidence apparatus and with a single channel Nal (Tl) scintillation spectrometer. A short description of the main features of the instruments is giv

A very recent publication by Guillaud, Pierre and Arnaud 1 on the preparation and reactivity in basic media of some cyclopropyl conjugated 1,2-diketones prompted us to report our synthetic results in the same field. In connection with our interest in

The behavior of the isomeric halogenobenzenesulfonic acids (halogen = F, Cl, and Br) in sulfuric acid was studied. In 115% H2SO4 at 25° only sulfonation takes place. Both the ortho- and para-isomers yield the 1-halogenobenzene-2,4-disulfonic acid, w
