A-Cyanocarboxylic acids

The a-bromo or a-chloro carboxylic acids 2 are versatile intermediates for further synthetic transformations. For example they can be converted into a-hydroxy carboxylic acids by reaction with water by reaction with cyanide a-cyanocarboxylic acids 7 are obtained, which can be further converted to...

Most dicarboxylic acids are prepared by adaptation of methods used to prepare monocarboxylic acids. Where hydrolysis of a nitrile yields a monocarboxylic acid, hydrolysis of a dinitrile or a cyanocarboxylic acid yields a dicarboxylic acid where oxidation of a methylbenzene yields a benzoic acid, oxidation of a di-methylbenzene yields a phthalic acid. For example ... [Pg.606]

Short pulses of laser radiation are used, typically at 337 nm, (nitrogen laser) but UV or infrared (IR) lasers can also be employed, depending on the matrix compound selected. Common matrix compounds are 2,5-dihydroxybenzoic acid, nicotinic acid, sinapinic acid, and a-cyanocarboxylic acid.6... [Pg.299]
