Y. Taniguchi et al., NOVEL DEOXYGENATIVE ACYLATION OF DIARYL KETONES WITH ACYLSILANES MEDIATED BY LANTHANOID METALS, Tetrahedron letters, 35(37), 1994, pp. 6897-6898
The reaction of diaryl ketones and benzoyltrimethylsilane is mediated
by lanthanoid metals such as ytterbium to give the deoxygenatively acy
lated product, I,I-diarylacerophenones in good yields. In the reaction
with acetylsilane, the corresponding silyl enol ether was obtained in
a moderate yield.
