The 1,2-FCl rearrangement reaction of a series of haloethanes is investigated by comparisons of the optimized ground- and transition-state geometries. Investigation of the effect of level of theory and basis set shows that the trends in threshold ene

The preparation and characterisation of two series of fluorinated chromia aerogel materials, lightly doped with zinc(II) or magnesium(II), are described. They behave as heterogeneous catalysts for transformations of 1,1,2-trichlorotrifluoroethane und

The collision-induced dissociation of C(2)X(5)(+) (C(2)Cl(2)F(3)(+), C(2)Cl(3)F(2)(+) and C(2)Cl(4)F(+)) and C(2)X(4)(+.) ions (C(2)ClF(3)(+*), C(2)Cl(2)F(2)(+*), and C(2)ClF(3)(+*)) derived from three chlorofluoroethanes (the isomeric 1,1,1- and 1,1

A [ 36 Cl ] radiotracer study of the behaviour of 1,1,2-trichlorotrifluoroethane on β-aluminium(III) fluoride at elevated temperature indicates that the isomerisation of CCl2FCClF2 to CCl3CF3 occurs by an intramolecular process. Isomerisation is fol

Two six-descriptor models, each descriptor derived directly from molecular structure, were fitted to the normal boiling points (Tb) of ethane plus the 52 known chlorofluoroethanes by multiple linear regression (s = 2.6 K, R2 = 0.998). Both models pre

The vibrational spectra of CClF 2 CH 2 Cl and CClF 2 CHCl 2 were measured, and the absorption bands were assigned on the basis of the scaled force field originally obtained by ab initio molecular orbital calculations. The scale factors were transfare

Reactions of chloroacetic acid with sulfur tetrafluoride and mesitylene give besides chlorofluoroethanes, small yields of 2-chloro-1,1-difluoro-ethylmesitylene and chloro- acetylmesitylene. Our results have shown that in the reaction of chloroacetyl-
