From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

One-pot cross-enyne metathesis (CEYM)–Diels–Alder reaction of gem-difluoropropargylic alkynes

open access: yesBeilstein Journal of Organic Chemistry, 2013
Propargylic difluorides 1 were used as starting substrates in a combination of cross-enyne metathesis and Diels–Alder reactions. Thus, the reaction of 1 with ethylene in the presence of 2nd generation Hoveyda–Grubbs catalyst generates a diene moiety ...

General Method for the Synthesis of (−)-Conduritol C and Analogs from Chiral Cyclohexadienediol Scaffolds

open access: yesMolecules, 2018
An efficient and facile general method for the synthesis of conduritol C analogs, taking advantage of an enantioselective biocatalysis process of monosubstituted benzenes, is described. The absolute stereochemical patterns of the target molecules (−

Unsymmetrical β‐Fused Blatter Radical Zinc Phthalocyanines

open access: yesChemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
Herein, we report the first synthesis of a new class of β‐fused Blatter–Zn phthalocyanines featuring a persistent radical π‐system, π–π‐driven crystal packing, and SOMO‐centered redox behavior. Single‐crystal X‐ray diffraction shows packing motifs dominated by centrosymmetric π‐π dimers.
