A new route has been found leading to the formation of pentafluorosulfuranyl arylenes. In its broadest aspect the process comprises:
effecting dehydrohalogenation or dehydrogenation of a pentafluorosulfuranyl compound represented by either of the structures:
wherein R
1
is H, C
1-10
alkyl, C
1-10
alkoxy, C
1-10
thionyl. C1-10 alkyl ether, list more, R
2
, R
4
and R
5
are H and R
3
is H repeated R
1
to form the pentafluorosufuranyl arylene represented by the structures:
wherein R
1
-R
5
are as represented in compound represented by the structures A and B.
