Aryloxysulphur(IV) fluorides

Abstract

Aryloxysulphur(IV) fluorides result from the interaction between aryl silyl ethers and sulphur tetrafluoride and its derivatives. The derivatives prepared [ArOSF₃(Ar = Ph; o-, m-, p- Tol; o-, m-, p- FC₆H₄; m-, p-ClC₆H₄), (ArO)₂SF₂(Ar = Ph; m-, p-Tol; m-, p-FC₆H₄; m-, p- ClC₆H₄; p-CF₃C₆H₄; p-O₂NC₆H₄), (ArO)₃SF (Ar = Ph or C₆F₅), (PhO)₄S, (C₆H₄O₂)₂S, ArOSF₂CF₃(Ar = Ph or C₆F₅), ArOSF₂C₃F₇(Ar =p-CF₃C₆H₄ or p-O₂NC₆H₄)] have been examined spectroscopically and in all cases the structures appear to be based on trigonal bipyramidal arrangements about the sulphur with the lone-pair equatorial and fluorines apical.
