Exaltation

The molar refraction deduced for alkyl derivatives, compared to the value obtained by addition, to the experimental molar refraction of thiazole, of the classical (CH2) increment of Eisenlohr Rch 4.618 cm ), show specific exaltations which are typical for each position of the thiazole ring (Table 1-49). [Pg.90]

The sydnones may be represented by structures (123a-d), of which the zwitterionic structure (123a) most clearly implies an aromatic sextet. The diamagnetic susceptibility exaltation for Af-phenylsydnone of ll.Ox 10 cm moP is comparable with the corresponding value for pyrrole (10.2x10 ). 3-p-Bromophenylsydnone (123 R = H, R = p-bromophenyl) is essentially planar however, the O—N bond and 0(1)—C(5) bond lengths are not very different from normal single bond distances. [Pg.34]

A more quantitative formulation of the varying resonance effects in electrophilic nuclear substitution reactions has been suggested by Tsuno, who has proposed to use Eq. (2), where Aa+ is a resonance exaltation term, and r is a susceptibility constant. [Pg.213]

Approximate pA exaltation due to methyl group, 0.7 (from pyrimidine and 4-methylpyrimidine ). [Pg.59]

Early work on the exaltation of the molecular refractivity of in-dazole and its 1- and 2-alkyl derivatives by Auwers and Diiesberg was considered to indicate that structure 18 represented the predomi-... [Pg.31]

The amino structure 173 was suggested for 5-aminoisoxazoles rather than the imino structure 174 on the basis of tentative chemical data and evidence from the exaltation of the molecular refractivity however, forms of type 175 were not taken into consideration in these... [Pg.66]

The molecular refraction of oxaziranes is in accordance with the values calculated from the individual refractions. For the isomeric nitrones, exaltation occurs. ... [Pg.91]

Most of the information available concerns SOMe and S02Me. Bordwell and his colleagues were the leading pioneers in determining sigma values for these groups. The results of the main determinations of the ordinary Hammett o constant and of the exalted constant o are shown in Tables 3 and 4 respectively. [Pg.498]

Having considered the main individual investigations of S02Me and SOMe in respect of their ordinary Hammett o constants and of the exalted constant o, we must examine... [Pg.503]

In their article on the Prediction of the strengths of organic acids Barlin and Perrin83 accepted McDaniel and Brown s82 a values for m- and p-SOMe and p-S02Me, but prefer Wepster s55 value for m-S02Me. They also quote 0.92 for the exalted constant for p-S02Me in phenols, but the basis for this is obscure. [Pg.504]

In Tabled theoretical magnetic anisotropies AK for selected molecules, calculated assuming the bond lengths shown in Fig. 5, are listed (in units of d.Kbenzene) d Compared with the experimental exaltations reported by Dauben et a/. . Theoretical values are in good agreement... [Pg.34]

Tables XXVIII and XXIX, respectively. Excellent correlations were obtained for all three sets. The stereochemistry of the sy -methyl ketoximes is discussed by Charton and Charton (73). The values of pj obtained for the trans-heterovinylene sets are not in good agreement with each other. Two sets gave values of 54 and 55, respectively, and the third set gave a value of 35. The difference in pj values cannot be accounted for. A value of 54 to 55 for pj suggests the possibility of some exaltation between substituent and reaction site such as that which occurs in para-substituted phenols and anilines. To demonstrate this with certainty requires that the value of pj be determined for a set of imines bearing a reaction site on the nitrogen which will not interact strongly with substituents. No such set of data is extant in the literature at the present time. Tables XXVIII and XXIX, respectively. Excellent correlations were obtained for all three sets.

The (Tj value for SOMe is slightly different from that given by Taft and Lewis . The continuous increase in a, produced by attached electronegative atoms at S or C is, of course, to be expected. This also encourages octet expansion as measured by The zero value for SOMe presumably means that any tendency to octet expansion [conventionally n (pd) conjugation] is essentially cancelled by the n (pp) conjugation of the sulfur lone pair. For these -f R substituents no exaltation of (Tj,-type values in the direction - (Tj would be expected. The table shows two (T -type constants phenol dissociation. We have already... [Pg.510]
