Fluorination by Sulfur Tetrafluoride

Abstract This chapter is an update of Chapter 1 of Volume 21 of Organic Reactions , based on the nearly 110 publications that have appeared from 1972 through 1982. Since the nature of the reaction and its mechanistic considerations have been clearly described in the previous chapter, they are not repeated. However, mechanisms involving the reaction of sulfur tetrafluoride with certain specific compounds are discussed under “Scope and Limitations”. Sulfur tetrafluoride continues to be one of the more common fluorinating agents, especially for relatively inert substrates. Its synthetic applications are summarized.
