Découvrez l'usage de
sulfonium salt dans la sélection bibliographique suivante. Des livres en rapport avec
sulfonium salt et de courts extraits de ceux-ci pour replacer dans son contexte son utilisation littéraire.
1
Handbook of Advanced Electronic and Photonic Materials and ...
The mechanism for the conversion of the sulfonium salt to the polymeric
precursor involves several steps, as shown in Scheme 8. The first two steps are
reversible and involve deprotonation by the base, followed by 1,6-elimination of a
sulfide ...

Here, for example, alkyl halide reacts first with the sulfide to produce a sulfonium
salt. R-S-R + R'X-»R2S-R'*X- (1-4) The sulfonium salt exchanges anions at the

Science of Synthesis: Houben-Weyl Methods of Molecular ...
There are a large number of sulfonium ylides that are stable enough to isolate
and fully characterize. Table 3 contains some representative examples of such
ylides prepared by deprotonation of a preformed sulfonium salt. Table 3

Photoinitiators for Polymer Synthesis: Scope, Reactivity, ...
This reaction forms an intermediate adduct cation radical structure, which then
reacts on another sulfonium salt to produce the oxiranium propagating cation and
a proton (in a way similar to that described in Scheme 12.5). The qualitative ...

Fig. 15. The varions gel times obtained with these mixtures are reported in Table
2 and ...

Thus, the amount of acid produced upon heating an SM hydrolysate at 100°C is a
measure of the extent of sulfonium salt formation. Accordingly, about 22% of the
original SM is found as sulfonium chloride after hydrolysis with 50 volumes of ...
