Selective trifluoromethylthiolation of heteroaromatic sp2 C–H bonds with the 2nd generation of trifluoromethanesulfenamide reagent
摘要:
By applying a well-established protocol of selective deprotonation of heteroarenes, the selective trifluoromethylthiolation of various heteroaromatic compounds has been performed, by using the 2nd generation of trifluoromethanesulfenamide reagent. With such strategy, functionalized heteroarenes could be synthesized as potential trifluoromethylthiolated building-blocks. (C) 2014 Elsevier B.V. All rights reserved.

Aliphatic compounds substituted with medicinally important trifluoromethylthio (SCF3) and trifluoromethylselenyl (SeCF3) groups were synthesized directly from alcohols by using the new benzothiazolium salts BT‐SCF3 and BT‐SeCF3. These bench‐stable fluorine‐containing reagents are facile to use and can be prepared in two steps from non‐fluorinatedheteroaromatic starting materials. The metal‐free d

Deoxygenative syntheses of fluorinated thioesters directly from carboxylic acids have been developed employing benzothiazolium reagents. The process using BT-SCF3 represents an attractive approach toward these SCF3-containing compounds that avoids the use of metal –SCF3 salts or preactivated acyl electrophiles. Moreover, the in situ activation of BT-SCF2H allows for an unprecedented nucleophilic d

sodium thiocyanate and the inexpensive, easy-to-use trifluoromethylating reagent Me3Si–CF3, diazoniumsalts are smoothly converted into the corresponding aryl trifluoromethyl thioethers. Combined with diazotisation, this convenient and inexpensive method allows the straightforward synthesis of aryl or heteroaryl trifluoromethyl thioethers from the corresponding anilines.
