Organic Synthesis: Aldol Condensation Reaction
In an "aldol addition" reaction an enol or enolate of an aldehyde or ketone reacts with a second aldehyde or ketone forming a new carbon-carbon bond which makes the aldol reaction an important reaction for organic synthesis. Originally, the aldol reaction used ethanal (see below) and therefore the product contained both an aldehyde and an alcohol functional group; thus it became known as the al...

متن کاملReaction of Formaldehyde with Phenols: A Computational Chemistry Study
Phenolic resins are important adhesives used by the forest products industry. The phenolic compounds in these resins are derived primarily from petrochemical sources. Alternate sources of phenolic compounds include tannins, lignins, biomass pyrolysis products, and coal gasification products. Because of variations in their chemical structures, the reactivities of these phenolic compounds with fo...
متن کاملThe condensation reaction of fatty acid biosynthesis. II. Requirement of the enzymes of the condensation reaction for fatty acid synthesis.
A yeast system differs only in that the major product is stearylCo.4 (5, 6) rather than the free fatty acid, palmitate, as in the other systems. The fatty acid synthetase reaction appears to be a multistage reaction catalyzed by a particulate enzyme complex estimated to have a molecular weight of 2,000,OOO in yeast (6) and to be readily sedimentable by ultracentrifugation in adipose tissue (4) ...
متن کاملFormation of dibenzodioxins and other condensation products from chlorinated phenols and derivatives.
Introduction Chlorodioxins can be formed in a two-step condensation reaction from ortho-substituted chlorophenoxy radicals or anions (1-3). The first route is of significance only where strongly oxidizing conditions exist such as a reaction of chlorine with pentachlorophenol at elevated temperature. For the second route we have investigated the condensation of alkali metal salts of chlorinated ...
