Preparation oftert-Butoxymethyl Phenyl Sulfone and Its Use in Synthesis as a Formyl Carbanion Equivalent

All articles of this category tert -Butoxymethyl phenyl sulfone can be readily prepared, metalated and condensed with alkyl halides. The homologous 1- tert -butoxyalkyl phenyl sulfones can undergo hydrolysis under very mild conditions to give corresponding aldehydes or methanolysis to give dimethyl acetals. tert -Butoxymethyl phenyl sulfone thus acts as a formyl carbanion or dimethoxymethyl carbanion equivalent.
