Aryloxy-derivatives of thionyl tetrafluoride
Abstract
Thionyl tetrafluoride reacts with arylsilyl ethers to give substituted derivatives ArO·S(:O)F3(Ar = Ph; o-, m-, p-MeC6H4; m-, p-ClC6H4; o-, m-, p-FC6H4), (ArO)2S(:O)F2(Ar = Ph, p-MeC6H4, p-ClC6H4, p-NO2·C6H4), (ArO)3S(:O)F (Ar = Ph, p-MeC6H4, p-ClC6H4, C6F5), (m-MeC6H4O)4SO, and (o-C6H4O2)2SO. Spectroscopic data and modes of thermal and hydrolytic decomposition were studied for most derivatives. The thionyl trifluorides and difluorides appear to have structures based on a trigonal bipyramidal co-ordination about sulphur.
