Stereochemistry of aldehyde dimethylhydrazone anions
Abstract
The structures of the anions formed by deprotonation of acetaldehyde dimethylhydrazone (DMH), propionaldehyde DMH, phenylacetaldehyde DMH, and trimethylsilylacetaldehyde DMH have been determined by 1H nuclear magnetic resonance spectroscopy, and limits for rotational barriers in these aza-allyl anions have been calculated.
