A boron radical contact ion-pair Mes2B{4-(3,5-dimethylpyridinyl)}K(18-crown-6)(THF) (1K) was isolated and characterized by ESR spectroscopy, UV-visible absorption spectroscopy and single crystal x-ray diffraction. The geometry, bonding and spin d. distribution are affected by the N···K interaction. The unpaired electron resides mainly on the boron atom and falls between those of triarylboron radical anions and neutral boron radicals. The work provides a novel boron-centered radical intermediate, connecting anionic and neutral boryl radicals. The experimental part of the paper was very detailed, including the reaction process of 4-Bromo-3,5-dimethylpyridine hydrochloride(cas: 1794738-16-1Safety of 4-Bromo-3,5-dimethylpyridine hydrochloride)
4-Bromo-3,5-dimethylpyridine hydrochloride(cas: 1794738-16-1) belongs to pyridine. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. As ligands, solvents, and catalysts they facilitate reactions; thus descriptions of these new ligands and their applications abound each year.Safety of 4-Bromo-3,5-dimethylpyridine hydrochloride
