A sensitive determination of alkanesulfonates combines RP-HPLC with an on-line derivatization procedure using fluorescent ion pairs followed by an online sandwich-type phase separation with chloroform as the solvent. The ion pairs are detected by fluorescence. With l-cyano-[2-(2-trimethylammonio)-ethyl]benz(/)isoindole as a fluorescent cationic dye a quantification limit for anionic surfactants including alkanesulfonates of less than 1 pg/L per compound for a 2.5-L water sample is established [30,31]. [Pg.168]

The cyano-substituted nitrile ylides 123 have been generated via 1,1-elimination reactions. For example, the benzyhdene derivative 122 (R=Ph) eliminated benzene on vapor phase pyrolysis to give 123 (R=Ph), which reacted via 1,5-electrocycli-zation [see also (66)] to give the isoindole 124 (41%) (67). In a similar way, 122 [R=(CH2)3CH=CH2] gave the corresponding nitrile yhde that reacted via intramolecular cycloaddition to give the pyrroline derivative 126. [Pg.491]

A route based on a benzyne intermediate can afford the isoindole ring via a category lb process. iV-Cyanomethyl-Af-methyl-0-chlorobenzylamine cyclizes to 1-methylisoindole under the influence of potassium amide in liquid ammonia (equation 36) (77T581). The cyano group plays two important roles. First, it provides stabilization of the carbanion... [Pg.323]

Aspartame and its degradation products aspartylphenylalanine, aspartic acid, and phenylalanine can also be separated after reaction with naphthalene-2,3-dicarboxaldehyde (NDA) in the presence of cyanide (sodium or potassium cyanide) in borate buffer (50 mM, pH 8). This reaction affords highly fluorescent and stable l-cyano-2-substituted-benz[/]isoindole (CBI) derivatives that can be detected at 420 nm excitation and 490 nm emission. The CBI derivatives are separated on a TSK ODS-120T column using a gradient of 30-80% B (acetonitrile water, 9 1 v/v) in A (50 mM acetate buffer, pH 6.0) (75). [Pg.538]

The methylene, cyano and nitro groups of compound (72.2) are involved in its conversion to an isoindole derivative by heating with a catalytic amount of ethanolic potassium acetate. [Pg.450]
