Exceptional numbering

Unfortunately, because of the exceptional number of interrelated equilibria between various rhodium clusters and Rh(CO) it seems unlikely that it will be possible to identify which rhodium species is responsible for the hydrogenation reactions. 

The eleven equations shown in Table VI express the activity of a group of Hill Reaction inhibitors (4-11). A common structural feature, in all the sets except Number 5, seems to be a nitrogen atom having considerable double bond character. Activity is... 

Photocycloadditions to the carbon-nitrogen double bond are in general less common, although this year an exceptional number of such transformations have been reported. The quinoxalinones (150), for example, are converted in this way into the azetidines (151) by addition to electron-poor alkenes (152). Azetidines have also been prepared from 3-aryl-2-isoxazonines. ... 

In this chapter we have not tried to cover the last decade (1990-2000) because of the exceptional number of new results. Only some general trends will be discussed.

Successful association between oleochemistry and thiol-ene reactions is demonstration of the immense potential of sustainable processes. A renewable resource as widely available as a vegetable oil, with the exceptional number of possibilities of molecules that can be obtained from it, together with a method as simple and efficient as the thiol-ene reaction, demonstrate that this strategy is much more than a tendency but instead a reality in polymer chemistry. 

Figure 10.13 is a bar-chart representation of the Class Projection output for factor 2 from a SIMCA, in which the modulus of the class distinctions is 10 or greater for all spectra except numbers 105, 115 and 125. The values for these spectra are about 7, 4 and 1 respectively, suggesting much less distinction (particularly for spectrum number 125), as might be expected from spectra recorded along a boundary region. A class distance plot of for the two main categories is shown in Figure 10.14. The transition from stroma to tumour along a row of spectra is clearly evident in the regions of spectra numbers 105, 115 and 125 the other crossovers occur at the end of each row of spectra in the grid-map, z.e., at spectra numbers 111 and 121.

Fig. M-20. From whence meat comes. Back of the meat on the table are 2,200,000 farms, of which 1,355,900 are cattle farms and ranches, 329,833 are hog farms, and 101,582 are sheep farms. All statistics are from the USDA, and for 1988, except number of cattle farms, number of hog farms, and number of sheep farms are from 1982 Agricultural Census.

The following scheme displays the (exceptional) numbering conventions that hold also for the fully unsaturated (mancude) basic skeleton, namely, 15H-cyclopenta[fl]phenan-threne.
