Reductive Arylation of Arylidene Malonates Using Photoredox Catalysis.
ACS Catalysis, 2019 A strategy with arylidene malonates provides access to β-umpolung single-electron species. Reported here is the utilization of these operators in intermolecular radical-radical arylations, while avoiding conjugate addition/dimerization reactivity that is

Lewis acid-catalyzed diastereoselective hydroarylation of benzylidene malonic esters [PDF]
, 2009 Herein we report that simple Lewis acids catalyze the hydroarylation of benzylidene malonates with phenols. Ultimately, 3,4-disubstituted dihydrocoumarins are obtained via a hydroarylation-lactonization sequence. Moreover, the dihydrocoumarins are formed

Pd‐Catalyzed C−C, C−N, and C−O Bond‐Forming Difunctionalization Reactions of Alkenes Bearing Tethered Aryl/Alkenyl Triflates [PDF]
, 2020 Over the past few years our group has described a new type of alkene difunctionalization reaction in which aryl or alkenyl triflates bearing tethered alkenes are coupled with various nucleophiles to afford carbocyclic products. The products are formed in

Supramolecular Gels as Active Tools for Reaction Engineering
Angewandte Chemie, EarlyView.The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Macromolecular Materials and Engineering, Volume 307, Issue 12, December 2022., 2022 Dibutyl itaconate (DBI) is tested as an environmentally friendly plasticizer for polylactide (PLA) with different proportions of DBI in the 2.5‐20 wt.% range. A co‐rotating twin‐screw extrusion process and injection moulding is employed for the manufacturing of the samples. As a result, noticeable increase in the elongation at break from 4.6% (neat PLA)

Angewandte Chemie, EarlyView.Benzamide‐directed iridium‐catalyzed branched selective and enantioselective C(sp2)‐H additions to minimally activated alkenes give tertiary and quaternary benzylic stereocenters under byproduct‐free conditions. The processes are enabled by a family of SPINOL‐based homochiral diphosphonite ligands.
