Related Condensation Reactions

When secondary amines are heated with ketones or aldehydes in the presence of an acidic catalyst, a related condensation reaction occurs and can be driven to completion by removal of water by azetropic distillation or use of molecular sieves. The condensation product is a substituted vinylamine or enamine. [Pg.32]

Aldol and related condensation reactions such as Knoevenagel and Claisen-Schmidt condensations are also widely used in the fine chemicals and specialty chemicals, e.g. flavors and fragrances, industries. Activated hydrotalcites have been employed as solid bases in many of these syntheses. Pertinent examples include the aldol condensation of acetone and citral [107, 108], the first step in the synthesis of ionones, and the Claisen-Schmidt condensation of substituted 2-hydroxyacetophenones with substituted benzaldehydes [109], the synthetic... [Pg.78]
