Adams, Christopher J. et al. published their research in Chemical Communications (Cambridge, United Kingdom) in 2015 | CAS: 628-13-7

Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Formula: C5H6ClN

Two-step solid-state synthesis of PEPPSI-type compounds was written by Adams, Christopher J.;Lusi, Matteo;Mutambi, Emily M.;Guy Orpen, A.. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2015.Formula: C5H6ClN This article mentions the following:

The two-step mechanochem. preparation of carbene-pyridine complexes of palladium and platinum is reported. The organometallic products, which represent a class of com. available catalysts, are rapidly formed in excellent yield proving solvent-free synthesis to be a viable synthetic alternative even in the case of NHC-containing compounds In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Formula: C5H6ClN).
