- REACTIONS OF HALOGEN FLUORIDES. XI. MECHANISM OF REACTIONS OF ALKYL HALIDES WITH BROMINE TRIFLUORIDE
-
The effects of the substituted halogen, the neighboring groups, and the polarity of the medium on the nature of the fluorination products were studied for the reactions of δ-substituted halogenobutanes and 1,2,3-trihalogenobutanes with bromine tetrachloride.A mechanism involving formation of linear halogenonium ions at the rate-determining stage is proposed.

- FLUORINATION OF HALOGENO ALCOHOLS WITH 1,1,2,3,3,3-HEXAFLUOROPROPYL DIETHYLAMINE
-
Fluorination of halogeno alcohols with 1,1,2,3,3,3-hexafluoropropyl diethylamine (PPDA) was investigated. 2-Bromo-1-fluorobutane was obtained from the reaction of PPDA and 2-bromo-1-butanol (yield 50percent).Similar results were obtained from other alipha

- Free Radical Substitution. Part 37. The Effect of Solvent on the Atomic Chlorination of 1-Substituted Butanes and Related Compounds
-
Experimental results reported in this paper show that the relative selectivity of atomic chlorination of 1-substituted butanes and related compounds is greatly influenced by the phase and by solvents.Solvents can be divided into three classes: (a) inert, (b) solvents which decrease the selectivity, and (c) solvents which increase the selectivity.The second group solvate the transition state and the third group solvate the chlorine atoms.
