3,5-Dibromopyridine C화학적 특성, 용도, 생산
화학적 성질
Light-Yellow Solid용도
3-Acetylamino-5-ethoxypyridine was prepared by converting 3, 5-dibromopyridine with sodium ethylate into 3-bromo-5-ethoxypyridine, allowing this substance to interact with ammonia and acetylating the aminoethoxypyridine thus formed with acetic anhydride. Lithiation of 3, 5-dibromopyridine with LDA and subsequent reaction with electrophiles provided 4-alkyl-3, 5-dibromopyridines 2 in high yield. Ligand was prepared by a Pd(0)-catalyzed cross-coupling reaction of 3,5-dibromopyridine and 5-tributylstannyl-3,3?-bipyridine. The synthesis of 3, 5-bis (2-indolyl) pyridine and 3-[(2-indolyl)-5-phenyl] pyridine derivatives as includes Stille or Suzuki type reactions, which were realized on the 3,5-dibromopyridine.주요 응용
3,5-Dibromopyridine (3,5-DBP) can be used for:(1) Spectroscopic analysis: FTIR and FT Raman spectra in the solid phase of 3,5-DBP and 3,5- dichloro-2,4,6-trifluoropyridine (3,5-DCTFP) were recorded in the regions of 4000-400 cm-1 and 3500-100 cm-1, respectively[1].
(2) Chemical reactions: 3,5-DBP can be reacted with phenyl isocyanate. chemoselective Staudinger-Phosphite reaction of 2,4,6-triazido-3,5-dibromopyridine azide moiety[2-3].
(3) Organic synthesis: Using 3,5-dibromopyridine as raw material can be used to prepare 3-acetamido-5-ethoxypyridine[4].
일반 설명
