1. Palladium‐Catalyzed Triarylation of sp 3 C−H Bonds in Heteroarylmethanes: Synthesis of Triaryl(heteroaryl)methanes

   https://doi.org/10.1002/adsc.201701347  

   Zhang, Shuguang ; Hu, Bowen ; Zheng, Zhipeng ; Walsh, Patrick J. ( February 2018 , Advanced Synthesis & Catalysis)

   A straightforward method for the palladium‐catalyzed triarylation of heteroarylmethanes at the methyl group has been developed. The reaction works with a variety of aryl halides, enabling the rapid synthesis of triaryl(heteroaryl)methanes in moderate to excellent yields.

2. Spectral diffusion and scaling of many‐body delocalization transitions

   https://doi.org/10.1002/andp.201600360  

   Gornyi, I. V. ; Mirlin, A. D. ; Polyakov, D. G. ; Burin, A. L. ( April 2017 , Annalen der Physik)

   We analyze the role of spectral diffusion in the problem of many‐body delocalization in quantum dots and in extended systems. The spectral diffusion parametrically enhances delocalization, modifying the scaling of the delocalization threshold with the interaction coupling constant.image

3. Synthesis of Tetrasubstituted α,β‐Unsaturated Aldehydes via Radical 1,4‐Aryl Migration/Trifluoromethylthiolation Cascade Reaction of Aryl Propynyl Ethers

   https://doi.org/10.1002/adsc.201700534  

   Guo, Chun‐Huan ; Chen, Dao‐Qian ; Chen, Si ; Liu, Xue‐Yuan ( August 2017 , Advanced Synthesis & Catalysis)

   A one‐pot synthesis of tetrasubstituted acrylaldehydesviadifunctionalization of aryl propynyl ethers has been achieved, which involves a trifluoromethylthiolation process and a radical 1,4‐aryl migration from oxygen to carbon. The reaction shows excellent conversion of aryl propynyl ethers into trifluoromethyl‐containing α,β‐unsaturated aldehydes through a radical pathway.

4. Selenolate Anion as an Organocatalyst: Reactions and Mechanistic Studies

   https://doi.org/10.1002/adsc.201701568  

   Trofymchuk, Oleksandra S. ; Zheng, Zhipeng ; Kurogi, Takashi ; Mindiola, Daniel J. ; Walsh, Patrick J. ( March 2018 , Advanced Synthesis & Catalysis)

   A new organocatalyst, the selenolate anion [RSe]^–, generated from bench‐stable and commercially available diphenyl diselenide or from phenyl benzyl selenide (10 mol%) is introduced. Benchmarking is performed in the conversion of benzylic chlorides intotrans‐stilbenes selectively at room temperature. Mechanistic studies support the intermediacy of the selenolate anion and of 1,2‐diphenylethyl phenyl selenide.

5. Palladium‐Catalyzed Enantioselective Decarboxylative Allylic Alkylation of Protected Benzoin‐Derived Enol Carbonates

   https://doi.org/10.1002/adsc.201901281  

   Lavernhe, Rémi ; Alexy, Eric J. ; Zhang, Haiming ; Stoltz, Brian M. ( November 2019 , Advanced Synthesis & Catalysis)

   The enantioselective palladium‐catalyzed decarboxylative allylic alkylation of fully substituted α‐hydroxy acyclic enol carbonates providing tetrasubstituted benzoin derivatives is reported. Investigation into the transformation revealed that preparation of the starting material as a single enolate isomer is crucial for optimal enantioselectivity. The obtained alkylation products contain multiple reactive sites that can be utilized toward the synthesis of stereochemically rich derivatives.
