Dimethyl acetals of mono and dinitrobenzophenones are easily prepared in quantitative yield by treatement with methanol and dimethylsulfite in the presence of continous hidrogen chloride stream. The new acetals were fully characterized by 1H-NMR, 13C-NMR,IR spectroscopy, MS(EI) and elemental analysis.
