Organosulfur chemistry sulfones

To a certain extent, the phenomenal expansion of organosulfur chemistry in recent years is also reflected in this review on rearrangements involving sulfones. It is hoped that this chapter, which is intended to serve all chemists, experts and students alike, will help them include its knowledge in their research programs, and will stimulate further creative work in the area. 

This chapter gathers together the principles behind these examples together with a discussion of what makes organosulfur chemistry special and also introduces new reactions. We have a lot to explain In Chapter 31 we introduced you to the Julia olefination, a reaction whose first step is the deprotonation of a sulfone. 

This review continues from one entitled The Chemistry of a,P-Unsaturated Sulfoxides which was recently published in a monograph of organosulfur chemistry. 1 In addition, the coverage has been extended to include the analogous a,P-unsaturated sulfones. The focus of the present review are recent advances in the chemistry of a,P-unsaturated sulfoxides and sulfones, especially those which have been published since 1993. The synthesis of a,P-unsaturated sulfoxides and sulfones has already been reviewed extensively by Rayner2 and hence will not be covered here. Only the chemistry of vinyl (alkenyl) sulfoxides and sulfones will be considered. The chemistry of other a,P-unsaturated sulfoxides and sulfones such as dienyl, allenyl, and propargyl (alkynyl) sulfoxides and sulfones is beyond the scope of this review. Considerable emphasis has been placed on stereo- and enantioselective reactions, reflecting the current interest in this area.
