Titanium(IV) is a powerful but selective Lewis acid which can promote the coupling of allylsilanes with carbonyl compounds and derivatives In the presence of titanium tetrachlonde, benzalacetone reacts with allyltnmethylsilane by 1,4-addition to give 4-PHENYL-6-HEPTEN-2-ONE. Similarly, the enol silyl ether of cyclopentanone is coupled with f-pentyl chloride using titanium tetrachlonde to give 2-(tert-PENTYL)CYCLOPENTANONE, an example of a-tert-alkylation of ketones.

In strong bases such as the one provided by sodium hydride and dimethyl sulfoxide (DMSO)—namely, dimsyl sodium—one should expect the formation of carbanions at sites of acidic protons. Ketones are attractive as potential sources of carbanions. However, ketone I features two blocked a carbons, without protons. Conversely, the tosyl group is ill suited for carbanion stabilization. The last functionality one may appeal to is the phenyl sulfone substituent at the end of the jec-pentyl chain. Recent investigations have revealed their potential as carbanion precursors, adding an important feature to their considerable usefulness in organic synthesis That is, sulfones can be removed under such mild conditions that carbonyl groups are not affected, and unconstrained a-sulfonyl carbanions have the unusual quality of retaining the asymmetry of their precursors in a wide variety of experimental conditions. ...

Esters (4.48) have one carbon substituent at the carbonyl and one -OR group. They are formed from acids and alcohols (Figure 4.11), and the name of the ester is a combination of the acid and alcohol names. The name of the alcohol used the form of a substituent, methyl, ethyl, phenyl, etc., and the acid part now takes the suffix -oate, to indicate the ester functionality. Thus 4.49 is methyl propanoate. The most common error that students make in naming esters is that they don t recognize the functional group and try to name them as substituted ketones. If you are finding the nomenclature of these difficult, it s often helpful to separate the ester into the acid and alcohol from which it was made. 4.50 was made from ethanoic (acetic) acid and 1-penta-nol hence, the name is 1-pentyl ethanoate or 1-pentyl acetate. In text, esters may be written as...
