Studies on the 1,2-brook rearrangement of bissilyl ketones
The first 1,2-Brook rearrangements with bis(dimethylphenylsilyl) ketone, initiated after addition of different C- and S-nucleophiles, are described. The resulting, newly formed carbanion can be trapped with electrophiles thus paving the way for utilizing bissilyl ketones as formyl dianion equivalents in the future. Georg Thieme Verlag Stuttgart.

Bissilyl ketone; A convenient method for the synthesis and its Pd(0) catalyzed reaction with alkenes and alkynes
A convenient method for the preparation of a bissilyl ketone is developed via a bissilyl ketone acetal as its precursor. The bissilyl ketone reacts with electron deficient alkynes and alkenes in the presence of Pd(0) catalyst to give bis-silylated products.
Synthesis, Molecular Structure, and Some Reactions of Bis(dimethylphenylsilyl)Ketone
The title compound was prepared from bis(methylthio)methane as a crystalline compound.The molecular structure was determined by X-ray crystallographic analysis, and reactions with alkyl metals and a Wittig reagent were examined.
