Example The mass spectra of both acetone and butanone show typical acyiium ion peaks at m/z 43, whereas the signals in the spectra of isopropyl ethyl thioether (Fig. 6.9), of 1-bromo-octane, (Fig. 6.10), and of isomeric decanes (Fig. 6.18) may serve as examples for carbenium ion signals. The superimposition of both classes of ions causes signals representing an average pattern. The properties of larger carbenium ions are discussed in the section on alkanes (Chaps. 6.6.1 and 6.6.3).

Thioxanthene 305 is readily metallated by -butyllithium at the 9-position giving access to the 9-carboxylic acid and the ethyl thioether. The latter gives the 9-carbanion on treatment with the superbasic mixture of n-BuLi, /-PoNH, and KO/-Bu, and hence gives access to 9-thioethylthioxanthene-9-carboxylic acid (Scheme 49) <1998T2251>.

The 2-(trimethylsilyl)ethyl thioethers are stable towards trifluoroacetic acid under conditions typically used to cleave acetals. The standard acylation and trans-esterification reactions are also fully compatible. Many Lewis acids are tolerated but halogenating agents react. Mild conditions for the cleavage of 2-(trimethyl-sily )ethyl sulfides, which are compatible with many of the standard transformations in carbohydrate chemistry, entails treatment of the thioether in dichloro-...
