Microscale Preparation of Isotopically Enriched 37ClHC=CHF

Chlorination of 1-bromo-2-fluoroethylene followed by reductive dehalogenation of the produced 1-bromo-1,2-dichloro-2-fluoroethane selectively affords 1-chloro-2-fluoroethylene. This process is suitable to produce 37Cl isotopically enriched ClHC=CHF on a convenient scale (3.8 mmol).

Experimental and theoretical studies of the vibrational spectra of cis-1-bromo-2-fluoroethene

The gas-phase infrared spectrum of cis-1-bromo-2-fluoroethene has been studied at low resolution in the range 200-6500cm-1, leading to a complete assignment of the fundamentals, except the lowest vibrational mode ν9 predicted at 167cm-1. The remaining vibrational structure has been mainly interpreted in terms of first overtone or two quanta combination bands. Isotopic 79/81Br shift has been observed only in the ν8 fundamental. The equilibrium structure and the quadratic force field have been investigated theoretically at CCSD(T) level of theory employing Dunning's correlation consistent triple-zeta basis set. Cubic and semidiagonal quartic force field have been calculated using second-order M?ller-Plesset perturbation theory and Ahlrich' split valence (SV) contracted basis set. After a minor scaled quantum mechanical (SQM) adjustment of the quadratic force constants, the vibrational analysis, based on the second-order perturbation theory, has been carried out with the calculated force constants.

Efficient microscale preparation of isotopically enriched 1-[ 79Br]bromo-2-fluoroethylene, [79Br]BrHC=CHF

An efficient preparation of 1-[79Br]bromo-2-fliioroethylene, [79Br]BrHC= CHF, was carried out by a three-step procedure: (a) natural 1-bromo-2-fluoroethylene, BrHC=CHF, was iodinated to 1-fluoro-2-iodoethylene, FHC=CHI; (b) 1-fluoro-2-iodoethylene was 79Br2-brominated to 1,2-di[79Br]bromo-1-fluoro- 2-iodoethane, [79Br]BrFCHCH[79Br]BrI; and (c) 1,2-di[ 79Br]bromo-1-fluoro-2-iodoethane was dehalogenated to 1-[ 79Br]bromo-2-fluoroethylene, [79Br]BrHC=CHF. The yield of isolated product, on a 2-mmol scale, was 62% with respect to 79Br2. Copyright Taylor & Francis, Inc.
