RSC Desktop Seminars in Organic Chemistry with the Brazilian Chemical Society 2020 are an initiative from the 萝莉社 and the Brazilian Chemical Society to bring cutting-edge research directly to you!
Covid-19 has exposed us to a new reality where the virtual world is much more important than before. In order to keep our students engaged at the frontiers of Organic Chemistry, we have organized a weekly webinar series that is a joint collaboration between the 萝莉社 (RSC) and the Organic Chemistry Division of the Brazilian Chemical Society (SBQ). It is an alternative way to share work and interact with potential collaborators.
The sections will alternate between Brazilian and international speakers, in some cases with the opportunity for a selected Brazilian early career researcher to engage with the audience by presenting their recent independent career developments.

TMS-Aryl Trifluoromethanesulfonates in Benzyne Chemistry: Limitations and New Challenges
Benzyne and its derivatives, called arynes, are highly reactive intermediates, with recognized importance in organic chemistry, successfully employed in syntheses of natural products and preparations of functional materials. In this context, TMS-aryl trifluoromethanesulfonates have emerged as an important alternative for the formation of benzyne and arynes under mild reaction conditions, enlarging the scope of benzyne chemistry applications in preparative organic chemistry. However, some limitations related to their synthetic routes still need to be overcome, for example, the requirement for n-butyllithium, that is, a strong and nucleophilic base, as well as the use of trifluoromethanesulfonic anhydride or bis(trifluoromethanesulfonyl)aniline as triflating reagents. Thus, through this lecture we intend to present our advances and some challenges involving the preparation of novel classes of aryne precursors.

Investigations on drug discovery and process development through photoredox and organocatalysis
Catalysis is a key technology in the pursuit of sustentability for a wide range of processes. In the last decades, photoredox and organocatalysis have been inserted in this scenario promoting more direct synthetic routes with optimization of time and energy. In this talk, I will present some recent advances from my research group in this area towards the synthesis of bioactive compounds and the development of processes employing immobilized organocatalysts in continuous flow systems.
