In a similar process, treatment of cyclic 1,3-diketones with aliphatic aldehydes in the presence of bf 3 et 2 leads to 1,3-dioxins (equation (52)), a reaction used in the synthesis of a plant growth regulator 〈82ajc1411, 88joc4314. 2-nitrobenzaldehyde, a valuable chemical intermediate, is produced by treating the alkali metal salt of a 2-nitrophenylpyruvic acid with an alkali metal hypochlorite in an aqueous medium to produce the corresponding 2-nitrobenzylidene chloride which, upon hydrolysis, yields the desired aldehyde. A novel method for the synthesis of 1,3‐diaryl‐2‐propene‐1‐ones via aldol condensation is introduced using socl2/etoh as a catalyst the hcl is the hcl is generated in situ by the reaction of socl 2 with absolute ethanol. For example, an aldol condensation reaction occurs in the synthesis of glucose, and the reverse of this reaction occurs in the catabolism of glucose the breakdown of fructose-1,6-bisphosphate into dihydroxyacetone and glyceraldehyde-3-phosphate in the second stage of glycolysis is an example of a reverse aldol reaction catalysed by the enzyme. 3-nitrobenzaldehyde (2172 mmol) and 1,2,4-triazole-4-amine (238 mmol) were mixed in 5 ml methanol and the mixture was refluxed for 3 hrs on water bath the white color product was obtained after the addition of 10 ml of ice water.
3-nitrobenzaldehyde, meta-nitrobenzaldehyde or m-nitrobenzaldehyde is an organic aromatic compound containing a nitro group meta-substituted to an aldehyde 3-nitrobenzaldehyde is the primary product obtained via the mono-nitration of benzaldehyde with nitric acid. Ring and imparts added stability the resulting product, 4-phenyl-3-butene-2-one, is the result from a single aldol condensation reaction between benzaldehyde and acetone.

The aldol condensation is a reaction that is named based on the type of product formed when two aldehydes (or ketones), in the presence of dilute base, yields a molecule having both alcohol and aldehyde functional groups. 1 07515g of 3-nitrobenzaldehyde was mix with 06ml acetophenone and 4ml of 95% ethanol in a conical flask the mixture was stirred until the entire solid is dissolved 2 05ml of sodium hydroxide solution (6g naoh solid in 10ml water) was added into the mixture and the stirring process continued.

A large number of more or less complicated ways of synthesis for the manufacture of o-nitrobenzaldehyde are previously known the method that is probably most widely known is the one involving an oxidation of o-nitrotoluene with chromic acid in acetic acid anhydride.
This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration the nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction, in which a proton of an aromatic ring is replaced by a nitro group. The wet crude nitrone is placed in a 3-l beaker a solution of approximately 6n sulfuric acid is then added, and the mixture is hand-stirred with a spatula or a glass rod crushed ice is added after 10 minutes, and the crude solid o-nitrobenzaldehyde is filtered, washed successively with dilute sodium bicarbonate solution and water, and dried. 8 aldol condensation: synthesis of indigo vat dyeing 63 u o nline edition for students of organic chem istry lab courses at the u niversity of colorado, boulder, d ept of chem and biochem 3 cooh acetone o-nitrobenzaldehyde 2 + 2+ 2 h 2 o indigo 8 aldol condensation: synthesis of indigo vat dyeing 65.
