The invention provides a process for producing a fluorine-containing compound from an inexpensive material.
Namely, Compound I such as R
A
CH
2
OH is reacted with Compound II such as XCOR
B
to form Compound III such as R
A
CH
2
OCOR
B
, followed by fluorination in a liquid phase to form Compound IV such as R
AF
CF
2
OCOR
BF
, which is converted to Compound V such as R
AF
COF and/or Compound VI such as R
BF
COF. R
A
is an alkyl group or the like, R
B
is a perhalogenoalkyl group or the like, R
AF
and R
BF
are fluorinated R
A
and R
B
, and X is halogen.
本发明提供了一种从廉价材料制备含氟化合物的方法。具体而言,化合物I(例如RACH2OH)与化合物II(例如XCORB)反应,形成化合物III(例如RACH2OCORB),随后在液相中进行氟化反应,形成化合物IV(例如RAFCF2OCORBF),然后将其转化为化合物V(例如RAFCOF)和/或化合物VI(例如RBFCOF)。RA是烷基或类似物,RB是全氟烷基或类似物,RAF和RBF是氟化的RA和RB,X是卤素。
