Carbanions formation by deprotonation

The Truce-Smiles rearrangement involves reaction of an internal carbon nncleophile [109] and differs from the Smiles reaction in that an activating group, such as a nitro group, may not be necessary. An early example, shown in Scheme 6.20, was the rearranganent of a phenyl sulfone to a sulfinic acid and involves carbanion formation by deprotonation of a methyl group by butyl lithium [110].
