Catalytic hydrotrifluoromethylation of unactivated alkenes.

A visible-light-mediated hydrotrifluoromethylation of unactivated alkenes that uses the Umemoto reagent as the CF(3) source and MeOH as the reductant is disclosed. This effective transformation operates at room temperature in the presence of 5 mol % Ru(bpy)(3)Cl(2); the process is characterized by its operational simplicity and functional group tolerance

Trifluoromethylation of allylsilanes under photoredox catalysis.

A new catalytic method to access allylic secondary CF3 products is described. These reactions use the visible light excited Ru(bpy)3Cl2·6H2O catalyst and the Togni or Umemoto reagent as the CF3 source. The photoredox catalytic manifold delivers enantioenriched allylic trifluoromethylated products not accessible under Cu(I) catalysis

Catalytic decarboxylative fluorination for the synthesis of tri- and difluoromethyl arenes.

Treatment of readily available α,α-difluoro- and α-fluoroarylacetic acids with Selectfluor under Ag(I) catalysis led to decarboxylative fluorination. This operationally simple reaction gave access to tri- and difluoromethylarenes applying a late-stage fluorination strategy. Translation to [(18)F]labeling is demonstrated using [(18)F]Selectfluor bis(triflate), a reagent affording [(18)F]tri- and [(18)F]difluoromethylarenes not within reach with [(18)F]F2

Self-tuning transmitter for fibre-to-the-antenna PON networks

WDM PONs offering point-to-point connectivity, independence of multiple access protocol to share the medium are good candidates for supporting the new fronthaul fibre network requirements. The necessity to allow inventory and maintenance cost reduction will favour WDM PON solutions based on colourless transceivers. We present the proposal of a network embedded self-tuning colourless transmitter, based on reflective semiconductor optical amplifier (RSOA) self-seeding architectures. We analyse the fibre-to-the-antenna network requirements and evidence the capabilities of the network embedded self-tuning colourless transmitter, showing its principle of operation, the development and the modelling of the active elements. We present and discuss recent experimental results up to 10 Gbit/s, which are encouraging for the transmitter exploitation in fronthaul WDM multiplexing technology
