SO 2 F 2 mediated transformation of pyrazolones into pyrazolyl fluorosulfates. Yusuke Adachi, Hiroshi Matsubara. For someone working at the interface of chemistry and biology, the impact of click chemistry has been larger than any other preparative methodology.
Since the seminal Sharpless click paper in , a tsunami of papers have reported new biocompatible reactions e. Sharpless research group has recently demonstrated the unique reactivity of sulfur—fluoride reagents of different valency in a series of seminal papers, Figure 1.
The potential of these products for further click chemistry through sulfur—fluoride exchange SuFEx reactions are also starting to be explored in the area of biomedical research. Although the general concept of SuFEx is still young, a recent review highlighted the present and historical chemistry of fluorosulfates 8 and the closely related functional groups sulfonyl fluorides, sulfamoyl fluorides, and sulfonimidoyl fluorides was reviewed by Suter in 9 and Sharpless in In this microreview, we aim to give an account on the synthetic chemistry around sulfonyl fluoride reagents, with a special focus on their applications in organic synthesis Click reagent, coupling partner, fluorinating reagent, and orthogonal reactivity.
Among the derivatives in Figure 1 , 2 , 10 sulfonyl fluoride reagents have the longest history as intermediates in organic synthesis and as reagents for covalent modification of enzymes before the concept of SuFEx chemistry was presented in Early Work with Sulfonyl Fluorides in Chemistry and Biology Sulfonyl fluorides were described already in the old German patent literature on chemical transformations and dye properties.
This makes selective CNS activity at reasonable levels highly challenging. A few other sulfonyl fluoride serine protease inhibitors have been reported in the literature, but none of them are specific for a particular serine protease family.
The building must then be ventilated, generally for at least 6 hours, before occupants can return. California regulations are such that the tent will be on for three to five days, which includes ventilation. In the US, sulfuryl fluoride must be transported in a vehicle marked with "Inhalation Hazard 2" placards.
The concentration is continuously monitored and maintained at the specified level using electronic equipment. Possible leakages are also checked by low range electronic detectors.

Yusuke Adachi, Hiroshi Matsubara. The most important loss process of sulfuryl fluoride is dissolution of atmospheric sulfuryl fluoride in the ocean followed by hydrolysis. Helal, and Christopher W. In this microreview, we aim to give an account of the synthetic chemistry surrounding sulfonyl fluoride containing substances from a historical perspective to present day developments.

Their synthesis demonstrated that the sulfonyl fluoride functional group were orthogonal to borane reduction, manganese dioxide oxidation, and a Horner—Wadsworth—Emmons transformation, Scheme Difluorocarbene Reagent: MDFA Introduction and Historical Background Molecules incorporating a sulfonyl fluoride functional group is currently attracting an enormous attention in the community of synthetic organic chemists.

Another popular method for preparation of sulfonyl fluorides is via Halex reaction from commercially available sulfonyl chlorides. Hoth, Jeffrey B. Zaton, V. In the improved method, the authors avoided the need to form diazonium salts, and instead made use of cheap, and readily available, aryl iodides as coupling partner for ESF. Ameduri, Polym.
