dc.description.abstractengThe content of this thesis focused on the general syntheses and applications S-substituted alkynyl-, alkenyl- and aryldibenzothiophenium triflates. Addition reactions have been performed from S-alkynyldibenzothiophenium triflates towards vinyl substituted ones. With these in hand, their abilities as potential Michael-acceptors and in photocatalysis were tested. Deprotonated acetylenes delivered diynes by electrophilic alkynylation with S-alkynyldibenzothiophenium triflates. Lastly, a family of S-aryldibenzothiophenium triflates has been synthetized. Postsynthetic modifications including ipso aminations as well as chemoselective suzuki couplings in the presence of common coupling partners such as iodides and triflates have been performed.de
