Aplicaciones

Benzynes were generated from o-(trimethylsilyl) phenols using nonafluorobutanesulfonyl fluoride (NfF) by a domino process.Nonafluorobutanesulfonyl fluoride (nonaflyl fluoride, C 4 F 9 SO 2 F, NfF) is the most widely used commercially available reagent for the synthesis of nonaflates.

Notas

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, moisture, baese..

Reagent for formation of nonafluorobutanesulfonates (nonaflates) of OH groups (compare Trifluoromethanesulfonic anhydride, A11767), e.g. with triethylamine in ether: Synthesis, 293 (1973); Liebigs Ann. Chem., 20 (1973).

Nonaflates of phenols, which are stable to flash chromatography, are attractive precursors for coupling reactions, with alkyl- and arylzinc halides, arylboronic acids (Suzuki) and arylstannanes (Stille), catalyzed by Pd(0) under mild conditions: J. Org. Chem., 63, 203 (1998). Silyl enol ethers, with catalytic TBAF in the presence of molecular sieves, are converted to enol nonaflates which undergo Heck couplings, e.g with styrenes to give 1,3-dienes: Synlett, 1141 (1997).
