Abstract: Abstract A new synthetic concept for π-conjugated oligomers has been developed by simply tuning the molar ratio between two co-monomers to switch the standard polymerization to one-step oligomerization. Three diketopyrrolopyrrole (DPP)-based conjugated oligomers sequentially consisting… read more here.

Abstract: A new type of organocatalyzed 1,3-thiosulfonylation has been developed to straightforwardly access highly functionalized vinyl sulfones, which features mild conditions, atom- and step-economy, practicability, conciseness, and environmental friendliness. Moreover, these valuable products can be transformed… read more here.

DOI: 10.1039/d2sc02790a
Abstract: Quaternary benzylic centers are accessed with high atom and step economy by Ir-catalyzed alkene hydroarylation. These studies provide unique examples of the use of non-polarized 1,1-disubstituted alkenes in branch selective Murai-type hydro(hetero)arylations. Detailed mechanistic studies… read more here.
