2-2-difluoro-2- ethanone

Under similar conditions, but with a load 482.4 kC mol the product 2,2-difluoro-l-phenyl-2-(phenyl-sulfanyl)ethanone was achieved in 73% yield. 

Earlier, Kutterer et al. (05BMCL2527) (Scheme 80) reported that 4-methyl-1,2-fazs(4-chlorophenyl)pyrazolidine-3,5-dione 348 with 2-bromo-l-(2,4-difluoro-phenyl)ethanone 349 in toluene containing DIPEA under MW heating (900 W) for 1 min gave 4 -alkyl-4-methyl-pyrazolidine-3,5-dione 350 and 4-methyl-5-alkyloxy-pyrazol-3-one 351. Although compound 351 was evaluated as new inhibitor of bacterial cell wall biosynthesis, no separation and yields of 350 and 351 were reported.
