New aryl sulphur pentafluorides are of formula (I). In (I), R = H, Y or a 1-15C alk(en) gp., opt. with Y substit(s)., in which one or more non-adjacent CH2 gps. can be replaced by -O-, -S-, -E-, -CO-, -O-CO-, -CO-O-, -O-CO-O-, -S-CO- and/or -CO-S-; E = CC or a gp. (II) or (III); XO = Y or Me; X = XO or H, Y = CN, N3, NCO, NCS, F or C1; A = (a) 1,4-cyclohexylene, in which one or 2 non-adjacent CH2 gps. can be replaced by O, opt. with one or 2 X substits.; (b) 1,4-phenylene, in which one or more CH gps. can be replaced by N, opt. with one or 2 X substits.; or (c) 1,4-cyclohexenylene, piperidin-1,4-diyl, bicyclo(2,2,2) octylene, naphthalen-2,6-diyl, decahydro naphthalen-2,6-diyl or 1,2,3,4-tetrahydronaphthalene; Z = independently -CO-O-, -O-CO-, -CH2CH2-, -CHCN-CH2-, -CH2-CHCN-, -CH=CH-, -CC-, -OCH2-, -CH2O-, -CN=N-, -N=CH-, -NO=N-, -N=NO- or a single bond; m = 0, 1 or 2; n = 1,2 or 3. The prepn. of (I) is claimed. |
