Reaction of carbene-stabilized diphosphorus, L:P-P:L (5) (L: = :C{N(2,6-Pri2C6H3)CH}2) with pyridine hydrochloride yields [L:(H)P-P:L]Cl (6), a salt containing the HP2+ cation-the elusive phosphorus analog of the well known diazonium cation, HN2+. In addition to reporting the synthesis and structure, the nature of (6) was further probed by DFT computations. Interestingly, carbenes may be employed to deprotonate (6), affording the starting material (5). In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7SDS of cas: 628-13-7).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.SDS of cas: 628-13-7
