Alkynes and polyynes can be used as linchpins in multicomponent and tandem reactions to provide rapid access to biologically pertinent terpenoid scaffolds. The alkyne fu nctional group also allows for the facile synthesis of novel nanographenes and contorted – even chiral – polycyclic aromatics. Alkynes even allo w for a mild\, non-oxidative (non-Scholl) bottom-up synthesis of atomicall y precise graphene nanoribbons (GNRs). \nAnnonce PDF de la conférenceInfo rmations supplémentaires \n  END:VEVENT BEGIN:VTIMEZONE TZID:America/Montreal X-LIC-LOCATION:America/Montreal END:VTIMEZONE END:VCALENDAR
