The relative importance of home and host innovation systems in the internationalisation of MNE R&D: a patent citation analysis [PDF]

This paper examines the phenomenon of home base augmenting (HBA) R&D and home base exploiting (HBE) R&D. It has three novelties. First, we argue that any given R&D facility’s capacity to exploit and/or augment technological competences is a function not ...

Installation of Trifluoromethylated Quaternary Carbon Stereocenters via Asymmetric Epoxidation of Tetrasubstituted Alkenes

Advanced Synthesis &Catalysis, EarlyView.
The catalytic enantioselective epoxidation of acyclic tetrasubstituted alkenes, bearing a trifluoromethyl group, is reported. In the presence of Takemoto's thiourea organocatalyst and tert‐butyl hydroperoxide, epoxides are obtained with excellent yield and good to high enantioselectivity.

Proton‐Coupled Electron Transfer Processes in the Decarboxylative Synthesis of C‐4 Substituted Chroman‐2‐Ones

Advanced Synthesis &Catalysis, EarlyView.
This research presents a new mild photocatalytic method enables C‐4 alkylation of chroman‐2‐one derivatives with primary alkyl radicals. This radicals are generated via oxidative PCET process. Developed approach offers broad substrate scope, scalability under photo‐flow conditions, and mechanistic evidence supports a decarboxylation pathway under polar

Electrochemical Trifluoromethylchlorosulfonylation of Alkenes via Copper‐Mediated SO2Cl Radical Transfer

Advanced Synthesis &Catalysis, EarlyView.
This article reports an electrosynthetic method for vicinal trifluoromethylchlorosulfonylation of alkenes using [Cu(MeCN)4]PF6 and triethylamine, without elaborate ligands. The reaction efficiently adds CF3 and SO2Cl across diverse unactivated alkenes with broad functional group tolerance.
