화학적 성질
Clear pale yellow-greenish liquid용도
1-Bromo-2-butyne is used in the preparation of six to eight annulated ring compounds in reaction with indoles and pseudopterane (+/-)-Kallolide B, which is a marine natural product. Further, it acts as a precursor in the preparation of axially chiral teranyl compounds, alkylation of L-tryptophan methyl ester, 4-butynyloxybenzene sulfonyl chloride and mono-propargylated diene derivative. In addition to this, it is also used in the synthesis of isopropylbut-2-ynylamine, allenylcyclobutanol derivatives, allyl-[4-(but-2-ynyloxy)phenyl]sulfane, allenylindium and axially chiral teranyl compounds.제조 방법
1-bromo-2-butyne is obtained by reacting 2-butyn-1-ol and organic solvent, pyridine.First react bromoethane with metal magnesium in THF to prepare Grignard reagent, then add paraformaldehyde to Grignard reagent for Grignard reaction, separate and recover after Grignard reaction 2-butyn-1-ol, then mix 2-butyn-1-ol with organic solvent and pyridine, add phosphorus tribromide dropwise for bromination reaction, separate and recover the product after bromination reaction.일반 설명
1-Bromo-2-butyne is a propargyl bromide derivative. It is one of the constitutional isomer of bromo butyne. Its Br-loss threshold photoionization breakdown diagram has been analyzed to derive dissociative photoionization thresholds to C4H5+ production. It participates in the preparation of linagliptin.1-BROMO-2-BUTYNE 준비 용품 및 원자재
