• 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).
