Hypervalent Sulfur

Our group has a long-standing interest in the chemistry of Sulfur (IV). The versatility of such reagents is a strong asset for the discovery of new reactivity and has resulted in several interesting observations.

(For an own review, see: Synthesis 2012, 175-183)


Key highlights include:

 

(a) the discovery of a novel Ylide Transfer process that relies on very simple reaction conditions and enables the preparation of sulfonium ylides in a single step



Angew. Chem. Int. Ed
. 2010, 49, 8979-8983

 

(b) the development of a arylation procedure that employs aryl sulfoxides as aryl donors; the connection between this process and the ylide transfer technology mentioned above is much closer that it may seem at first glance!

(c) the discovery that the sulfur ylides made accessible through ylide transfer are excellent starting materials for several interesting transformations, including an intriguing direct cyclopropanation reaction
