Usage

General Description

1,1-Difluoro-1,2,3,3-tetrachloropropene is a chemical compound that contains four chlorine atoms and two fluorine atoms attached to a propene backbone. It is primarily used as a refrigerant and as a precursor in the production of other chemicals. 1,1-DIFLUORO-1,2,3,3-TETRACHLOROPROPENE is classified as a hazardous substance due to its potential to cause skin and eye irritation, as well as respiratory effects if inhaled. It is also considered to be an environmental hazard, as it can persist in the atmosphere and contribute to ozone depletion. Due to its potential health and environmental impacts, proper handling and disposal practices must be observed when using 1,1-difluoro-1,2,3,3-tetrachloropropene.

PHOTOCHEMICAL REDUCTION OF CARBON-HALOGEN BONDS. 3. REGIOSELECTIVITY OF THE REACTION IN FLUORINATED HALOGENOPROPANOATES.

The ester group exhibits a strong directive effect in the photochemical reduction of a carbon-halogen bond and directs the reduction in perhalogenated chlorofluoropropanoates of the type CFXY-CClZ-COOR (X,Y,Z = Cl, F) to the α-position in the acyl part of an ester.The reduction takes place with the same regioselectivity even in esters CFCl2-CHCl-COOR (10).In esters containing an α -CCl2- group the reductions to the first and the second stages can be separated and the individual reduction products can be obtained preparatively.The α C-F bond is more difficult to reduce and therefore in the ester CFCl2-CHF-COOR (11) the β C-Cl bond was reduced specifically and in the ester CF2Cl-CHF-COOR (12) both the α C-F bond and the β C-Cl bond were reduced parallely.The relative reactivity of fluorinated halogenopropanoates with an α C-Cl bond showed only small differences in the reduction with 2-propanol in the presence of acetone as a sensitiser; the quantum yield Φ reached values of about 28-35 under kinetic measurements and thus proved the existence of a chain radical mechanism.
