Lipase-mediated epoxidation of alkenes in supercritical carbon dioxide

Green Chemistry Letters and Reviews, 2018
In this work, supercritical carbon dioxide was used as reaction media in the lipase-mediated epoxidation of alkenes for the first time. Under the optimal conditions (alkene (1 mmol), novozym 435 (15 mg), H2O2 (50% aqueous solution, 1.4 mmol), n-caprylic ...

Anomeric Amide‐Enabled Alkene‐Arene and Alkene‐Alkene Aminative Coupling

Angewandte Chemie International Edition
AbstractDespite the prominence of C−N bond forming cross‐coupling reactions as a strategy to assemble molecular fragments, aminative coupling approaches, in which two fragments are assembled directly at the heteroatom, represents a rarely exploited retrosynthetic strategy. Herein, we report the design, synthesis, and implementation of an anomeric amide

Advancing Electronic Application of Coordination Solids: Enhancing Electron Transport and Device Integration via Surface‐Mounted MOFs (SURMOFs)

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...
