The reductive cleavage of aromatic dimethyl acetals and ketals, 1, with Li metal in THF at low temperature allows the generation of stable α-alkoxy-α-arylsubstituted carbanions, avoiding the Wittig rearrangement. Reaction of these carbanions with various electrophiles afforded the expected products 2. Further in situ reaction of compounds 2 afforded the products of reductive electrophilic disubstitution, 3.
