Abstract
The first 1,2-Brook rearrangements with bis(dimethyl-phenylsilyl) 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.
Key words
Brook rearrangement - bissilyl ketones - formyl anion - organolithium species - silyl migration
