Abstract
PURPOSE: To obtain the titled compound suitable to a heavy metal adsorbent for uranium etc., an ion exchange resin (intermediate), etc., by reacting a specific fluorine compound with a pyrophosphite in the presence of a free radical initiator.
CONSTITUTION: The first fluorine compound having a group of -CF2X or formula I (X is Br or I), preferably a perfluorocarbon compound, is reacted with a pyrophosphite of the formula Y2P-Z-PY2 [Y is Cl or OR1 (R1 is lower alkyl), etc.; Z is O or S], preferably tetraethyl pyrophosphite, in the presence of a free radical initiator, preferably an organic peroxide, e.g. di-tert-butyl peroxide, preferably at 60W120°C for 2W6hr, to give the aimed second fluorine compound having a group of -CF2PY2 or formula II, e.g. perfluoro-4-oxa-5-hexenesulfonic acid dichloride of formula III.
