Fig. 1.11 Robert Scott, Edward Wilson, and Ernest Shackleton left their base at Hut Point on November 2 of 1902 and traveled across the Ross Ice Shelf to a point near the mouth of the Beardmore Glacier at 82°16 S. They attempted to use dogs but ended up man-hauling their sleds because their dogs died or were killed. They returned on February 3 of 1903 after 93 days on the trail during which they traveled 1,320 km for a daily average of about 14 km per day. All three suffered from snow blindness, scurvy, and exhaustion. This trip opened the way for Scott s quest to reach the geographic South Pole during his second expedition from 1910 to 1913 (Adapted from Stonehouse 2002, p. 46)...

This group of five men (Robert F. Scott, Edward Wilson, Lawrence Titus Oates, Edgar Evans, and Henry Birdie Bowers) reached the South Pole on January 18 of 1912. They were profoundly disappointed and demoralized when they discovered that Amundsen and his men had reached the Pole about 1 month before them on December 14 of 1911. The Norwegians had set up a black tent at the Pole which contained a letter addressed to the King of Norway, a... 

In contrast to organic chemistry, where extensive studies have attempted to correlate nucleophilicity with various parameters (e.g., the Swain-Scott, Edwards, and Ritchie equations), there is currently little quantitative information concerning nucleophilic reactivities toward coordinated ir-hydrocarbons. Recent kinetic studies of reactions shown in equations (10) and (11) have established... 

The following overall nucleophilicity order for Sn2 mechanisms (in protic solvents) was given by Edwards and Pearson RS > ArS >1 >CN > OH > Nj > Br > ArO > Cl > pyridine > AcO > H2O. A quantitative relationship (the Swain-Scott equation) has been worked out similar to the linear free energy equations considered in Chapter 9 ...

Taxonomic nomenclatures for plants and animals are under constant revision. In the Handbook of Chemical Risk Assessment series, the author elected to conform as much as possible to the systems and spellings used by Scott and Wasser (1980) for plants, Swain and Swain (1948) for insects, Turgeon et al. (1988) for aquatic molluscs, Williams et al. (1989) for decapod crustaceans, Pratt (1935) and Hyman (1940, 1951a, 1951b, 1955) for miscellaneous invertebrates, Robins et al. (1991) for fishes, Ditmars (1966) for reptiles, Edwards (1974) and Howard and Moore (1991) for birds, and Nowak and Paradiso (1983) for mammals. Individual species are arranged alphabetically by scientific and common names (Table 33.2). In total, about 2300 species of animals and plants were cited, of which only 23 (1.0%) were listed in at least 20 chapters. The most widely cited species include ... 

On February 21, 1809, Hatchett became a member of the famous Literary Club which had been founded in 1764 by Dr. Samuel Johnson and Sir Joshua Reynolds (51). As treasurer of the club, Hatchett prepared a brief historical account of it, which appears in Boswell s Life of Johnson (25). The club also included, among others, Edmund Burke, Oliver Goldsmith, David Garrick, Edward Gibbon, Adam Smith, Sir Joseph Banks, Sir Charles Blagden, Sir Humphry Davy, Dr. W. H. Wollaston, Sir Walter Scott, Sir Thomas Lawrence, and Dr. Thomas Young.

Second-order rate constants for the reactions of phenacyl bromide with a number of anionic or neutral nucleophiles in 3 2 (v/v) acetone-water have been measured at several temperatures.141 Correlation analysis with the Bronsted equation or Swain-Scott equation is not satisfactory. Better results were obtained with the two-parameter Edwards equation. 

Correlation of nucleophilic rate data for phenyldimethylsulfonium ions with common nucleophiles, with pX e values shows that the slopes of the lines, jS[ e, correlate qualitatively with the Edwards hardness parameter for the nucleophile and not with the Swain-Scott n parameter.144 cw,cw-2,4,6-Trimethyl-l,3,5-triaminocyclohexane is weakly basic in aqueous solution, because of steric inhibition to solvation of the conjugate acid.145 The three NH2 groups are axial and the steric effect also results in reduced reactivity as a nucleophile in, S n2 reactions. Highly stereoselective syntheses of N-. and O-glycosides have been carried out by addition of anionic nucleophiles to glycosyl iodides.146 5 n2 reactions are involved, but some substrates are susceptible to E2 elimination when treated with highly basic anions. 

In general this analysis shows that the behaviour which the Swain-Scott relation attempts to describe is governed by both kinetic and thermodynamic contributions. The mix of the two contributions (Table 6 and Fig. 11) is different for different nucleophiles. This is probably the reason why the Swain-Scott relation does not hold for a large number of reactions (Leffler and Grunwald, 1963b Koskikallio, 1972) and why more complicated expressions, such as the Edwards relation (Edwards, 1954), have been proposed.
