● Siv: 1-Bromo-2-butyne yog siv rau hauv kev npaj rau rau yim rau yim lub nplhaib annulated nyob rau hauv cov tshuaj tiv thaiv nrog indoles thiab pseudopterane (+/-)-Kallolide B, uas yog marine natural khoom.Tsis tas li ntawd, nws ua haujlwm ua ntej hauv kev npaj ntawm axially chiral teranyl compounds, alkylation ntawm L-tryptophan methyl ester, 4-butynyloxybenzene sulfonyl chloride thiab mono-propargylated diene derivative.Ntxiv rau qhov no, nws kuj tseem siv rau hauv kev sib txuas ntawm isopropylbut-2-ynylamine, allenylcyclobutanol derivatives, allyl-[4-(tab sis-2-ynyloxy)phenyl] sulfane, allenylindium thiab axially chiral teranyl compounds.
1-Bromo-2-butyne, tseem hu ua 1-bromo-2-butene los yog bromobutene, yog ib qho organic compound nrog cov mis molecular C4H5Br.Nws yog cov kua tsis muaj xim uas feem ntau yog siv los ua cov tshuaj reagent hauv cov organic synthesis.1-Bromo-2-butyne feem ntau siv hauv cov tshuaj tiv thaiv organic los qhia cov bromine atom rau hauv ntau lub molecules.Nws reactivity raws li ib tug electrophile ua rau nws pab tau nyob rau hauv kev npaj ntawm lwm cov organic tebchaw, xws li tshuaj, agrochemicals, thiab tej yam ntuj tso khoom. Ntxiv rau nws cov tshuaj synthesis daim ntaub ntawv, 1-bromo-2-butyne kuj yog siv nyob rau hauv kev tshawb fawb thiab kev loj hlob.Nws qhov tshwj xeeb reactivity thiab muaj peev xwm ua rau muaj kev cuam tshuam ntau yam, xws li hloov pauv, ntxiv, thiab tshem tawm cov tshuaj tiv thaiv, ua rau nws muaj txiaj ntsig rau kev kawm cov tshuaj tiv thaiv thiab tsim cov txheej txheem hluavtaws tshiab.Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias 1-bromo-2-butyne tuaj yeem ua tau. txaus ntshai thiab yuav tsum tau saib xyuas.Nws yog cov nplaim taws heev thiab yuav ua rau khaus lossis kub hnyiab thaum sib cuag nrog daim tawv nqaij lossis qhov muag.Kev tiv thaiv kev nyab xeeb kom raug, xws li hnav cov khoom tiv thaiv thiab ua haujlwm hauv qhov chaw muaj cua zoo, yuav tsum tau ua raws li thaum tuav cov khoom sib xyaw no.
