N. Kamigata et al., REACTIONS OF TRICHLOROMETHANESULFONYL CHLORIDE AND CARBON-TETRACHLORIDE WITH SILYL ENOL ETHERS CATALYZED BY A RUTHENIUM(II) PHOSPHINE COMPLEX, Journal of organometallic chemistry, 552(1-2), 1998, pp. 39-43
The reactions of trichloromethanesulfonyl chloride with trimethylsilyl
enol ethers of acetophenones in the presence of a ruthenium(II) phosp
hine complex gave 1-aryl-3,3-dichloropropen-1-one together with alpha-
chloroacetophenones. The product ratio depended on the substituent on
the aromatic ring of the silyl enol ether. The reactions of carbon tet
rachloride with the silyl enol ethers under similar conditions afforde
d 1-aryl-3,3-dichloropropen-1-one in good yield. (C) 1998 Elsevier Sci
