Difluorocarbene is the
chemical compound with
formula CF2. It has a
short half-life, 0.5 and 20 ms, in
solution and in the gas phase, respectively. Although...
-
involves pyrolysis to give
difluorocarbene,
which dimerizes: 2 CHClF2 → C2F4 + 2 HCl The
compound also
yields difluorocarbene upon
treatment with strong...

Pyrolysis of
chlorodifluoromethane (at 550–750 °C)
yields TFE, with
difluorocarbene as an intermediate. CHCl3 + 2 HF → CHClF2 + 2 HCl 2 CHClF2 → C2F4 +...
- easily.
Decarboxylation of
sodium chlorodifluoroacetate generates difluorocarbene: CF2ClCO2Na → NaCl + CF2 + CO2
Decarboxylations are an

- is
difluorocarbene, CF2,
which is a
singlet whereas carbene (CH2) has a
triplet ground state. This
difference is
significant because difluorocarbene is...

fluorocarbon gases and a sublimate,
including tetrafluoroethylene (TFE) and
difluorocarbene radicals (RCF2). An
animal study conducted in 1955
concluded that it...

Tetrafluoroethylene is
generated via the
intermediacy of
difluorocarbene: CHClF2 → CF2 + HCl 2 CF2 → F2C=CF2 The
