A simple synthesis of 2-methyl-1,3-dithiolium and related cations

open access: yes, 2007
3 pages.A simple, high-yielding synthesis of 2-methyl-1,3-dithiolium tetrafluoroborates is reported. The reaction of these salts with N,N-dimethylformamide and acetic anhydride gives rise to the previously unreported N,N-dimethyl 2-(1,3-dithiol-2-yliden ...

Recent application of acidic 1,3-azolium salts as promoters in the solution-phase synthesis of nucleosides and nucleotides [PDF]

open access: yes, 2018
Acidic 1,3-azolium salts are prepared from Brønsted acids and 1,3-azoles such as imidazole, thiazole, and oxazole. Acidic imidazolium salts are frequently employed as promoters for the synthesis of nucleotides using the phosphoramidite method in a ...

Programming Palladium Cage Geometry through Ligand Redox Modulation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
A neutral redox‐active exTTF ligand (L) forms a Pd2L4 cage, whereas its oxidized form (Lox) yields a Pd2(Lox)2 macrocycle. Lox further assembles with a dibenzothiophene derivative (L′) into Pd2(Lox)(L′)2 and Pd4(Lox)4(L′)4 architectures. Reduction of Pd2(Lox)2 and Pd2(Lox)(L′)2 restores the parent Pd2L4 cage, enabling redox controlled nuclearity ...

Phosphazene Base Mediated (sp3)CH Functionalization with CO2 and CS2

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 24, August 29, 2025.
Selective deprotonation of HCF3, HC2F5, and CH3CN by the phosphazene base EtP4 in the presence of CO2 or CS2 affords the phosphazenium carboxylates [EtP4H]+[F3CCO2]− and [EtP4H]+[F5C2CO2]−, as well as the corresponding dithiocarboxylates [EtP4H]+[F3CCS2]− and [EtP4H]+[F5C2CS2]−.
