Absorption spectra of formazans have been studied in detail. Almost all formazans exhibit UV/visible spectra between 300 and 600 nm.1,2,12,13,40,62,325 326 The absorption maxima are very sensitive to substituent effects. For example, the 1,5-diphenyl formazan 185 when X is hydrogen, methyl, phenyl, cyano, and mercapto shows a band at 420, 410, 470, 504, and 590nm in ethanol, respectively. The 3-chloro derivative 186 when X is hydrogen, iodine, bromine, chlorine, and fluorine has a band at 433,433,430,421, and 417 nm, respectively. Table 13 shows the influence of substituents on the absorption maxima in the trisubstituted formazans 3. Table 14 shows the influence of substituents on the absorption maxima of...

A single ortho- (8a) or para- (8b) methyl substituent has no influence on the rate of cyclization of the singlet tolylnitrene to the azirine (Fig. 10, Table 4, Scheme 3). Spin localization effects are not observed as with cyano and phenyl substitution. Cyclization of 2,6-dimethylphenyl or 2,4,6-trimethylphenylnitrenes necessarily proceeds towards a carbon bearing a substituent. The steric effect raises the barrier to cyclization by 1.5-2.0kcal/mol, in excellent agreement with the predictions of Karney and Borden. The steric effect extends the lifetime of 2,6-dimethylphenylnitrene at ambient temperature to 13 ns in freon-113 and of 2,4,6-trimethylphenylnitrene to 8 ns, in the same solvent.

Chlorine atoms in (trichloromethyl)benzenes which have fluoro, chloro, dichloromethyl, chloroformyl, cyano, isocyanato, jV-phthalimino or methyl substituents in the ring are substituted by fluorine using antimony(III) fluoride (Swarts reaction).3 4 2-(Trifluoromethyl)phen-yl isocyanate, 4-chloro-2-(trifluoromethyl)phenyl isocyanate, 2,4- and 2,5-bis(trifluoro-methyl)phenyl isocyanate, and 2,4-bis(trifluoromethyl)-l,5-phenylenc diisocyanate can be obtained in this way.5... 

If solutes dissolve only in nonpolar or weakly polar solvents, the decision tree suggests that we try reversed-phase chromatography. Our choices include bonded phases containing octadecyl (CJg), octyl, butyl, ethyl, methyl, phenyl, and cyano groups.

The actual magnitude of the interaction of a given substituent with the adsorbent depends on the adsorbent, other substituents present, and the type and rigidity of the backbone of the diastereomeric analytes. Although no serious attempts at quantification have been made, repulsive interactions toward silica and alumina can be ranked roughly as H < methyl < phenyl = ethyl < tert-butyl < triliuoromethyl < a-naphthyl < 9-anthryl = pentafluoroethyl < heptaliuoroethyl. Size and hydrophobicity are both relevant incorporation of polar functionality (hydroxyl, carbalkoxy, cyano) leads to attractive rather than repulsive interactions with silica.

Other polyethylene-type polymers are made from monomers containing chloro, methyl, cyano, and phenyl substituents, as summarized in Table 22.7. In each case the double carbon-carbon bond in the substituted ethylene monomer becomes a single bond in the polymer. The different substituents lead to a wide variety of properties. 

The anthranilic acid may also be converted into phenyl glycine ortho-carboxylic acid by the action of formaldehyde and potassium cyanide, yielding first cyano-methyl anthranilic acid which on hydrolysis is converted into the phenyl glycine compound. 

Similar reactions were observed when 1 -phenyldiazoethane was allowed to react with methyl ( )-2-cyano-3-(4-substituted phenyl)acrylates in dichloromethane at — 5 to 0 °C. The expected cyclopropanes, methyl 1 -cyano-3-methyl-3-phenyl-2-(4-substituted phenyl)cyclopropanecarb-oxylates 2, were formed in moderate to low yields. In addition, significant amounts of methyl 2-cyano-4-phenyl-4-(4-substituted phenyl)pent-2-enoates 3, formed by rearrangement from postulated dihydropyrazole intermediates, and methyl 4-cyano-3-methyl-3-phenyl-5-(l-phenyT l-(4-substituted phenyl)ethyl]-4,5-dihydro-3f/-pyrazole-4-carboxylates4, formed by 1-phenyldiazoethane attack on 3, were obtained. ...
