Cu(I) Arylsulfonate π-Complexes with 3-Allyl-2-thiohydantoin: The Role of the Weak Interactions in Structural Organization

Acta Chimica Slovenica, 2020
The present work is directed toward preparation and structural characterization of two novel Cu(I) arylsulfonate π-complexes with 3-allyl-2-thiohydantoin, namely [Cu2(Hath)4](C6H5SO3)2 (1) and [Cu2(Hath)4](p-CH3C6H4SO3)2·2H2O (2) (Hath = 3-allyl-2 ...

Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes

Angewandte Chemie, EarlyView.
The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...

Oxygen‐Tolerant, Controlled Synthesis of Degradable and Water‐Soluble Poly(Vinyl Amide)s via Radical Ring‐Opening Copolymerization of Cyclic Dithiothreitol

Angewandte Chemie, EarlyView.
Oxygen‐tolerant photoinduced electron/energy transfer reversible addition–fragmentation chain transfer (PET‐RAFT) polymerization enables the controlled radical ring‐opening (rROP) copolymerization of cyclic dithiothreitol (cDTT) with less‐activated vinyl monomers, affording degradable polymers with predictable molecular weights, low dispersities, and ...

Engineering Rapid Payload Release Rate in 1,6‐Elimination Processes of Self‐Immolative Linkers

Angewandte Chemie, EarlyView.
The payload release rate of self‐immolative linkers was greatly improved through stabilization of an intermediate carbocation, thereby achieving an up to 10 000‐fold improvement in rate constant. Furthermore, lipophilicity was identified as another factor that affects the release rate. This new strategy is applicable to different payloads and different
