摘要：

Oligomeric addition products formed between lithium t-butoxide and one, two, three or more equivalents of trichloroacetaldehyde were trapped by acetylation and then identified by gas chromatography and proton nuclear magnetic resonance spectroscopy. Individual diastereomers were recognized. Product formation was found to be sensitive to both the addition and endcapping temperatures employed.
