With benzaldehyde

Benzal derivatives. Primary aromatic amines generally condense directly with benzaldehyde to form benzal derivatives (Schiff s bases or anils) ... [Pg.653]

Here the phenylacetic anhydride, possessing more reactive a-hydrogen atoms, condenses with benzaldehyde to give a-phenylcinnamic acid. The preparation of the latter is an example of the Oglialoro modiflcation of the Perkin reaction. [Pg.708]

The synthesis of 3-phenyl-]-(2-pyridyl)-2-propen-]-one (2.4c) via an aldol reaction of 2-acetylpyridine with benzaldehyde has been described in the literature ". O jmpound 2.4a-e have been prepared in high yields, using slightly modified versions of these literature procedures. [Pg.50]

Diamino-4-phenylthiazole condenses with benzaldehyde, yielding 2-amino-4-pheny]-5-benzalaminothiazole (241). [Pg.47]

The reactivity of 2-methylselenazole toward carbonyl compounds is the same as its thiazoie homolog. Reaction of 2,4-dimethylselenazole with benzaldehyde in the presence of anhydrous zinc chloride as catalyst gives 4-methyl-2-styrylselenazoie [m.p. 74-75 C (19)] (Scheme 43). [Pg.249]

Erlenmeyer et al. also examined the behavior of 4-methyl-, 4,5-dimethyl-, and 5-methylthiazole in the reaction with benzaldehyde at 160°C in the presence of ZnClj (439, 510) they were able to show that neither the 4- nor 5-methyl groups reacted under these conditions and that the condensation occurred at the sole unsubstituted 2-position (Scheme 114). [Pg.144]

Asinger and Thiel (473) use an aldehyde and ammonia instead of nitrile. Thus the reaction of mercaptoacetone. with benzaldehyde and ammonia gives 4 methyl-2-phenylthiazole in 80% yield and 4-methyl-2-pheny]-A-4-thiazoline as the main by-product. [Pg.293]

The greater reactivity of 2- and 4-alkylquiQolines allows them to condense with benzaldehyde to produce 2-P-styrylquinoline [4945-26-0] and... [Pg.395]

Alkyl Isoquinolines. Coal tar contains small amounts of l-methylisoquinoline [1721-93-3] 3-methylisoquinoline [1125-80-0] and 1,3-dimetliylisoquinoline [1721-94-4J. The 1- and 3-methyl groups are more reactive than others in the isoquinoline nucleus and readily oxidize with selenium dioxide to form the corresponding isoquinoline aldehydes (174). These compounds can also be obtained by the hydrolysis of the dihalomethyl group. The 1- and 3-methyhsoquinolines condense with benzaldehyde in the presence of zinc chloride or acetic anhydride to produce 1- and 3-styryhsoquinolines. Radicals formed by decarboxylation of carboxyUc acids react to produce 1-aIkyhsoquinolines. [Pg.398]

Benzylarnine, [100-46-9] CgH CH2NH2 (bp, 184°C at 101.3 kPa) produced by reaction of ammonia with benzaldehyde and hydrogenation of the resulting Schiffs base, is used as the raw material for the production of biotin (Vitamin H), as an intermediate for certain photographic materials, and as an intermediate in the manufacture of certain pharmaceutical products. [Pg.35]

Dibenzjiamine, [103-49-17, CgH CH2NHCH2CgH (bp, 300°C at 101.3 kPa) is produced by reaction of benzyl amine with benzaldehyde and hydrogenation of the Schiffs base. It is used in mbber and tire compounding, as a corrosion inhibitor, and as an intermediate in the production of mbber compounds and pharmaceutical products. [Pg.36]

Acetalation. As polyhydroxy compounds, carbohydrates react with aldehydes and ketones to form cycHc acetals (1,13). Examples are the reaction of D-glucose with acetone and a protic or Lewis acid catalyst to form l,2 5,6-di-0-isoprop5lidene-a-D-glucofuranose [582-52-5] and its reaction with benzaldehyde to form 4,6-0-benzyhdene-D-glucopyranose [25152-90-3]. The 4,6-0-(l-carboxyethyhdine) group (related to pymvic acid) occurs naturally in some polysaccharides. [Pg.481]

Pyrolytic Decomposition. The pyrolytic decomposition at 350—460°C of castor oil or the methyl ester of ricinoleic acid spHts the ricinoleate molecule at the hydroxyl group forming heptaldehyde and undecylenic acids. Heptaldehyde, used in the manufacture of synthetic flavors and fragrances (see Elavors and spices Perfumes) may also be converted to heptanoic acid by various oxidation techniques and to heptyl alcohol by catalytic hydrogenation. When heptaldehyde reacts with benzaldehyde, amyl cinnamic aldehyde is produced (see Cinnamic acid, cinnamaldehyde, and cinnamyl... [Pg.154]

For the reactions of methylpyridazine 1-oxides with benzaldehyde in the presence of sodium methoxide, the order of reactivity of methyl groups at various positions is 5 > 4,6 > 3. 3-Methylpyridazine 1-oxide is converted by acetic anhydride into the 3-acetoxymethyl compound, which is easily hydrolyzed to 3-hydroxymethylpyridazine. [Pg.32]

Pyrrolo[2,3-6]pyridine, 2-methyl-Reimer-Tiemann reaction, 4, 508 Pyrrolo[2,3-6]pyridine, 4-methyl-hydrogen exchange, 4, 502 reaction with aldehydes, 4, 503 reaction with benzaldehyde, 4, 511... [Pg.822]

Triphenylethylene has been prepared by the reaction of phenylmagnesium bromide with benzyl benzoate, with desoxy-benzoin, or with ethyl pheaniylacetate, and by the reaction of diphenylketene-quinoline with benzaldehyde. The above procedure is an adaptation of that described by Hell and Wiegandt. ... [Pg.90]
