Isotopomer Distributions of Neutral Products from a Doubly Labeled Cation in the Gas Phase. Interconversion of 1-Fluoro-1-propyl Cation and 1-Fluoroisopropyl Cation on the C3H6F+ Potential Energy Surface

The title cations CH3CH2CHF+ (3) and CH3CHCH2F+ (4) are formed as transient intermediates in the gas phase.These are labile on the millisecond timescale as free ions but can be intercepted in ion-neutral complexes.When 3 is generated as free cation by reaction of CF3+ with propionaldehyde, it rearranges to (CH3)2CF+ (1), as shown by recovery of 2-fluoropropene as a neutral product from its deprotonation in an EBFlow experiment.The same neutral product is recovered when 1 is produced directly by reaction of acetone with CF3+ in the EBFlow.Neutral productsindicative of 3 and 4 (allyl fluoride and 1-fluoropropene) are recovered when these cations are formed in + PhO.> ion-neutral complexes by electron bombardment of CH3CDFCH2OPh (6).Analysis of the isotopic distribution in the recovered neutrals from EBFlow radiolysis of CH3CDF*CH2OPh (where the asterisked carbon is 13C-labeled) allows an assessment of the primary rearrangement pathways.The distribution of label is assayed by using 19F NMR.Rearrangement of the R+ moiety to form deuterated 1 occurs in about half of the complexes formed.In the remainder, methyl transfer (to form deuterated 3) is 2-3 times faster than fluoride transfer (to form deuterated 4).Scrambling of deuterium in the neutral products provides evidence that 3 and 4 interconvert within the ion-neutral complexes.

KINETIC STUDY OF CHEMICALLY ACTIVATED FLUOROCYCLOPROPANE.

The photolysis of ketene at 313 nm was studied in the presence of fluoroethene and oxygen. The product formation was observed as a function of total pressure between 12 and 1080 mbar. Chemically activated fluorocyclopropane was formed by addition of singlet methylene to the double bond, and subsequent isomerization to the fluoropropenes as well as decomposition of these primary products to allene, propyne and HF was observed. The product yield was described by RRKM calculations; a stepladder deactivation model was used.

Bestimmung der Geschwindigkeitskonstanten der Reaktion von 1CH2 mit Fluor- und Chlorethen

The rate constants for the addition of 1CH2 to fluoroethene and chloroethene have been determined using the known rate constant for the reaction of 1CH2 with ketene.The experiments yielded the results k4a(296 K) = (8.2 -/+ 0.6)E13 cm3 mol-1 s-1 k4b(296 K) = (2.9 -/+ 0.4)E13 cm3 mol-1 s-1. - Keywords: Chemical Kinetics / Gases / Photochemistry / Radicals

SYNTHESE D'ETHYLENIQUES MONOFLUORES

Monofluorinated ethylenic compounds have been prepared by action of potassium tertiobutylate either on 2-fluorotosylates or 2-fluorochlorides.In the case of 2-fluorochlorides the action, at higher temperature, of basic salt such as KF in ethylene glycol, may be used to prepare monofluorinated ethylenics compounds.
