Abstract
N-Nonaflylbenzotriazole reacts with trimethylsilyl enol ethers in tetrahydrofuran at room temperature under tetrabutylammonium fluoride catalysis to afford o-(nonafluorobutylsulfonamido)phenylhydrazones in 19-82% yield. N-Nonaflylbenzotriazole reacts twice with the less sterically demanding silyl enol ethers to afford the corresponding o-(nonafluorobutylsulfonamido)phenylazo enols in 41-75% yield.
Key words
benzotriazole - hydrazones - ring opening - silyl enol ether
