Questions on selectivity of homo- and crossaldol condensation of lower aldehydes at presence of different salts of amines.

Reactions of homo- and crossaldol condensation of formaldehyde and acetaldehyde were studied at presence of primary, secondary and tertiary amine salt of linear structure in N,N-dimethylacetamide, water and toluene. It was found that in all solvents conversion of reagent is increased with increase o...

Description
Summary:Reactions of homo- and crossaldol condensation of formaldehyde and acetaldehyde were studied at presence of primary, secondary and tertiary amine salt of linear structure in N,N-dimethylacetamide, water and toluene. It was found that in all solvents conversion of reagent is increased with increase of bacity of amine, but selectivity on cross-reaction became lower because of formation side products of acetaldehyde homo-condensation. The conversion of acetaldehyde is also increased with increase of solvent polarity.
