Pyridinium Salts of Dehydrated Lanthanide Polychlorides [PDF]
Molecules, 2022 The reaction of lanthanide (Ln) chloride hydrates ([Ln(H2O)n(Cl)3]) with pyridine (py) yielded a set of dehydrated pyridinium (py-H) Ln-polychloride salts. These species were crystallographically characterized as [[py-H-py][py-H]2[LnCl6]] (Ln-6; Ln = La,

Nickel‐Catalyzed Synthesis of Dialkyl Ketones from the Coupling of N‐Alkyl Pyridinium Salts with Activated Carboxylic Acids [PDF]
Angewandte Chemie - International Edition, 2020 While ketones are among the most versatile functional groups, their synthesis remains reliant upon reactive and low abundance starting materials. In contrast, amide formation is the most-used bond construction in medicinal chemistry because the chemistry
