Treatment of aromatic ketones or aldehydes with a lanthanide metal and chlorotrimethylsilane in tetrahydronfuran in the presence of isopropanol provided good yields of the corresponding pinacols. This pinacolic reductive coupling was not observed with aliphatic ketones or aldehydes.

Key words: AROMATIC ALDEHYDE, REDUCTION, DYSPROSIUM, LANTHANUM, PRASEODYMIUM, PROTON MAGNETIC RESONANCE SPECTROMETRY, KETONE, INFRARED SPECTROPHOTOMETRY
