SF5-Synthons: Pathways to Organic Derivatives of SF6

In this review, the synthesis and use of the primary synthons SF5X (X = F, Cl, Br, SF5) in forming organic derivatives of SF6 will be described. We have found that using primary SF5X synthons, convenient pathways exist for preparing secondary synthons that include SF5 - alkanes, alkenes, alkynes, iodides and aromatics. The primary synthons also offer pathways for preparing and studying the reactive SF5+, SF6-, and SF5· intermediates.
