3-Hydroxy-2,2-dimethylpropionaldehyde: equilibria and structure of its dimer
Abstract
The structure and stereochemistry of the dimer of 3-hydroxy-2,2-dimethylpropionaldehyde (1) has been deduced by i.r. and n.m.r. spectroscopy. Equilibria involved in solutions of (1) have been observed and discussed. It has been proved that the dimer is a mixture of two stereoisomers, of which the cis is more stable.
