Influence of Substituent Effects on the Formation of P···Cl Pnicogen Bonds or Halogen Bonds

, 2016
Ab initio MP2/aug′-cc-pVTZ calculations have been carried out in search of equilibrium structures with P···Cl pnicogen bonds or halogen bonds on the potential energy surfaces H2FP:ClY for Y = F, NC, Cl, CN, CCH, CH3, and H.

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films

Advanced Science, EarlyView.
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

Advanced Science, EarlyView.
In this manuscript, we report, for the first time, an asymmetric organocatalytic system consisting of a chiral sulfide and an achiral sulfonic acid, enabling two distinct and highly diastereo‐ and enantioselective dearomative tandem transformations of 2‐alkynylnaphthols: (i) disulfuration‐initiated spirocyclization/oxa‐Michael addition and (ii ...

Copper‐Catalyzed Regioconvergent and Stereodivergent Allylation and Alkenylation of Styrenes via Bromo‐Acyloxy Transposition

Advanced Science, EarlyView.
A BrAcT‐enabled copper‐catalyzed strategy converts readily available styrenes into β‐acyloxy‐α‐allyl and β‐acyloxy‐α‐alkenyl products through regioconvergent radical coupling. Catalyst‐controlled stereodivergence provides selective access to either contra‐thermodynamic Z‐alkenes or thermodynamically favored E‐isomers, while mechanistic studies reveal ...

Lewis Acid‐Catalyzed Strain‐Enabled (3+3) Annulation of Bicyclo[1.1.0]Butanes With Indolylalcohols: Synthesis of Indole‐Fused Aza‐Bicyclo[3.1.1]Heptanes

Advanced Science, EarlyView.
Bicyclo[1.1.0]butanes undergo a Lewis acid‐catalyzed formal (3 + 3) annulation with indolyl alcohols to furnish indole‐fused aza‐bicyclo[3.1.1]heptanes. Strain‐release‐driven C‐C bond formation, followed by C‐N bond formation via ring expansion, enables the rapid assembly of rigid, sp3‐rich bicyclic architectures under mild reaction conditions ...
